Q: My husband told me a month ago that he has started to eat lunch with a single lady in his office. He says they're only friends and feels sorry for her since she is new to the company. I told him I didn't feel comfortable with him eating with her alone and asked if some other co-workers could eat with them as well. He said there isn't anyone else to sit with them. Am I being too paranoid, or should I insist that he stop?

Jim: Your concerns are warranted. Your husband may genuinely feel sorry for his co-worker and have a desire to make her feel welcome at the office. But consistent one-on-one time with her is not a healthy idea. Most people who fall into extramarital affairs didn't set out to do so. Rather, the illicit relationship began on innocent terms.

There are always compelling reasons to be cautious about opposite-sex friendships outside of one's spouse. Before you were married, you may have had lots of friends of the opposite sex, but things are different now. Once you say, "I do," your bond with your spouse takes priority over every other relationship.

An excellent book on maintaining appropriate boundaries in marriage is "Hedges," by Jerry B. Jenkins. If your husband is willing, you might consider reading it together. But make sure he knows that your desire to read the book is motivated not by suspicion, but rather a desire to make your relationship as healthy and strong as possible. You might also consider taking Focus on the Family's Couple Checkup (www.family.org/couplecheckup), which will help both of you evaluate the strengths and weaknesses in your relationship.

Q: I found some very inappropriate texts and pictures on my teenage son's cellphone the other day. I know when I confront him, he will be devastated that I know. How can I approach this so that he understands it's wrong to do this without scarring him for life?

Dr. Greg Smalley, Vice President, Family Ministries: Confronting your son about inappropriate behavior won't scar him for life, but allowing that behavior to continue unchecked just might.

The first thing he needs to know is that sexting is potentially illegal. He could face arrest and prosecution for sharing or receiving explicit pictures over the phone. If the subjects are minors, the pictures fall into the category of child pornography, the distribution and possession of which is strictly illegal in every state.

Will your son be embarrassed when you confront him about this? Probably. So when you do confront him, make sure he knows that you're doing so out of a deep love for him and a concern for his emotional and spiritual well-being.

This will require you to walk a very fine line. If you make light of the situation and dismiss the seriousness of the mistake your son has made, you increase the likelihood that he'll repeat the behavior. On the other hand, if you take an excessively hardline approach, you run the risk of driving your teen into even deeper despair.

Even as you endeavor to address the situation with love and compassion, then, there can be no question of minimizing the anguish your son is experiencing. The key to successfully managing this situation is to help him take ownership of that anguish, assume responsibility for the actions and choices that produced it, and turn it into a springboard to better, wiser behavior in the future. If you need help with this crucial process, don't hesitate to contact Focus on the Family for a consultation with a member of our counseling team.

Q: My husband and I just moved to another state so he could get his MBA. Last night, he told me that he's been having an affair for a few months. He says he doesn't love me any longer, but feels obligated to stay with me. I don't have anyone here to talk with and I don't have any support, so I'm at a loss as to what I should do. Do I try to work it out with him? Should I move back home? There are so many emotions in my head, and I don't feel stable enough to make any life-changing decisions. All I have left is my faith. Please help!

Jim: We're very sorry to learn of your heartbreaking situation. At a time like this, you absolutely need a support network in place. Even though you're new in the area, we urge you to seek out a pastor or a women's church group with whom you can share your struggles.

In addition, you should enlist the help of a qualified marriage counselor. If your husband is willing to attend counseling with you, encourage him to do so. But even if he isn't, you need the input and assistance of a third party. Contact Focus on the Family (focusonthefamily.com) for a free consultation with a member of our counseling team and for a referral to a counselor in your area.

One thing is for certain: Continuing the affair (even if your husband technically stays married to you out of "obligation") should not be an option. You need to force a crisis and give him an ultimatum. If he wants to continue the affair, he's going to have to find someplace else to live. He has to understand that his adulterous behavior will not be allowed to continue under any circumstances. If separation is what it takes to open his eyes and stimulate some self-examination on his part, then so be it. May God grant you strength and wisdom during this difficult time.

Q: What do you think about a woman who is dating a younger man? I'm in my 30s and he is in his 20s. Do these types of marriages typically work?

Dr. Greg Smalley, Vice President, Family Ministries: There is surprisingly little research in this area. However, one study by the U.K. Office for National Statistics found that there is not a strong association between marital age difference and the likelihood of divorce.

Research aside, I think what you're really asking is, "Can this relationship work?" In my years of counseling, I have encountered many married couples who have built strong relationships despite what might be considered a significant age difference. You say you're in your 30s and he's in his 20s, but that doesn't tell me much. The difference between 28 and 31, for example, is likely to be much less significant than the difference between 39 and 21.

In the end, though, age is just a number. Some 23-year-olds have a much greater degree of maturity and character than their 40-something counterparts. If your relationship progresses and marriage enters the picture, you'll want to consider the same things with a younger man that you would with one who is similarly aged. Are you compatible in terms of beliefs, maturity and so on? Is he trustworthy?

I'd recommend that you and your boyfriend take Focus on the Family's Couple Checkup at www.family.org/couplecheckup. It's a practical, in-depth way to test your compatibility and strengthen your relationship. There are versions of the Couple Checkup for dating, engaged and married couples.

Q: I've never kept tight controls on my teenagers. I don't enforce strict curfews or get uptight when they come in late at night. But recently, I read an article about sexual slavery and human trafficking in our community, and it left me deeply unsettled. Am I overreacting?

Jim: Human trafficking is a terrible reality that impacts not only the developing world, but middle-class neighborhoods right here in the U.S. So yes, you need to be aware of this dark underside of contemporary culture.

At the same time, alarmist fears are helpful to no one. You don't want to scare your kids unnecessarily. Nor is it wise to convey an attitude of suspicion or distrust to your teens without good cause. Statistically, they face far greater danger from simply riding in an automobile every day than they do from the possibility of trafficking.

You know your kids best, and you're in the best position to determine whether they might be vulnerable to this kind of deception and victimization. Are they troubled in any way? Do they struggle in school? Are they slipping academically, dealing with social rejection or facing bully problems? Are they new in the neighborhood, unpopular with their classmates, insecure or low on self-esteem? If so, their innate desire for some kind of human connection could make them easy targets.

The best way to prevent this is to make sure you're building strong relationships with your kids. The family should be their primary point of connection. You can protect them against all kinds of negative outside influences by forging a bond of mutual trust. Make it clear that they can always come to you with their needs, problems and concerns.

While your first responsibility is to your own kids, it's also important for everyone to do their part to ensure their communities are safe. Keep your radar up for signs of suspicious activity in your community. If, at any point, you come across evidence that your children or anyone else you know have become caught up in human trafficking, contact local authorities or call the National Human Trafficking Hotline at 888-373-7888.

Q: My wife has "given up drinking" several times only to end up back on the bottle. She's lost her job, our household is showing signs of neglect, and the whole family is slowly going to pieces. What can I do to reverse this negative trend?

Dr. Greg Smalley, Vice President, Family Ministries: We're very sorry to learn about this painful situation. One thing is for certain: You can't navigate it alone. Your wife, especially, needs to enlist outside help to combat her addiction.

The Lighthouse Network is a clearinghouse for substance abuse referrals. People there can help you locate a facility in your area that will help your wife take some positive steps toward recovery. They can also provide information regarding the insurance companies that are prepared to work with these facilities. You can contact Lighthouse Network at 1-877-562-2565.

Another option for long-term treatment of alcoholism is the Salvation Army. This service is offered free of charge. Visit www.salvationarmyusa.org for information regarding local treatment centers. You can also find out about local Alcoholics Anonymous groups at www.aa.org.

Finally, you should think about enlisting the help of a qualified professional, not only to help your wife, but to help your entire family navigate these difficult waters. Contact Focus on the Family (focusonthefamily.com) for a free consultation with one of our staff counselors, as well as a referral to long-term counseling in your area. God bless you and your family as you go through this dark time together.
