DEAR ABBY: I am a community college sophomore (age 20) in an international honor society, double-majoring in biotechnology and biological sciences. My dream is to become a cardiologist.

I have worked hard and excelled at my studies, as well as in my friendships and sports. However, my brothers have not. My older brother, "Aaron," barely graduated from community college and my younger brother, "Greg," dropped out after his first semester.

I know it's not healthy for me to think this way, but I am afraid I am going to be the one who has to support them. Aaron plays video games all day, while Greg does nothing. I'm afraid I'll be stuck playing "Mommy" for my adult brothers for the rest of my days.

How do I get across to them that they're not children anymore and they need to take their education seriously? -- NOBODY'S MOMMY IN MARYLAND

DEAR NOBODY'S MOMMY: Where are your brothers living now? With your parents? If that's the case -- and I suspect it is -- that message should come from them. That your parents would allow Aaron to sit around all day playing video games rather than become independent means they are his enablers.

There is truth to the saying, "The Lord helps those who help themselves." Warn the boys that unless they start preparing for their future, they could wind up living in the street, because when your parents go, you have no intention of supporting them financially. That responsibility is not and should not be yours.

DEAR ABBY: I just got married to a beautiful woman. She's tall and elegant. The problem is, she's addicted to taking pictures of herself. She takes at least 100 of them a day.

When we're driving, she's busy taking selfies. When we go out, she asks me to take pictures of her. If I tell her I don't want to take more pictures, she pleads with me to take "just one more," which really means five.

When we are out to dinner and I get up to go to the restroom, she asks total strangers to take her picture. When we were on vacation and we went to the pool, she wore full makeup for two reasons, she said: (1) She's not putting her head under water, and (2) she wants some pictures taken of her.

I have told her many times how much this annoys me, but she says I am preventing her from what she enjoys. What can I do to help her? -- TOO MANY PHOTO OPS

DEAR TOO MANY PHOTO OPS: You have married a beautiful (tall, elegant) piece of arm candy. Because you did not mention even one other positive quality about her, I assume this is what you wanted. Her vanity/insecurity about her looks is the "accessory" that goes with your trophy.

It will take effort on your part to help her recognize that what she has to offer beneath the surface is at least as important as her looks. (It may also take the services of a psychologist, if she's willing.)

DEAR ABBY: My fiancee and I have known each other since high school. I was the "good kid" with honors and the right parents. She was considered trouble and didn't have the best home life. Rumor had it that she moonlighted as a stripper our senior year, but I always blew it off as false.

Fast-forward 12 years: I ran into her recently, and we decided to have dinner. I fell in love with her on that date. A few months went by and I mentioned the rumors. She wasn't upset and matter-of-factly explained that she did start stripping in high school and continued through college. It bothered me, but the benefits of being with her far outweighed the negatives.

Now that we are engaged, she told me she had to "come clean." She said there were times in college when she had sex with some of her regular clients. I am floored. She basically admitted she had prostituted herself. I don't know what to do. I don't want to blame her for her past indiscretions, but this is a big deal. I don't know how to let it go. Advice, please! -- GUY WHO NEEDS ADVICE

DEAR GUY: You now see your fiancee clearly -- warts and all. The problem with "falling in love" (what I define as infatuation) is that you don't yet know who the person IS. Regardless of how your fiancee financed her education, she deserves respect for being honest with you. She has done as much as she can to improve her life. You must now ask yourself if you can see past her past, and if she is someone you would be happy spending the rest of your life with. Remember, I live in Los Angeles, and in this town, her revelation wouldn't necessarily be a deal-breaker.

DEAR ABBY: I met a guy named "Ryan" about 10 weeks ago. We hit it off right away. I admit I had a little crush on him.

About a week after we met, he came out to a group of our mutual friends (me included) as gay. I'm very supportive of him, and it didn't change anything between us at all. Over the last several weeks, we have grown to be best friends and continue to grow closer and closer.

Once I found out Ryan was gay, the rational and practical part of me took over and squashed the crush I had on him in the beginning. But now that feeling is coming back even stronger.

I know our relationship can never be anything more than platonic. I guess I'm just asking how I can get over him while still maintaining our close friendship, because ultimately, that means the world to me, and I don't want to lose it. -- FRIEND ONLY, IN WASHINGTON, D.C.

DEAR FRIEND ONLY: It's not easy to think rationally when emotions are involved. Ryan may have everything you want in a man, but he will not be a romantic partner for you. If spending time around him becomes too painful, you may have to put some distance between the two of you until you regain your emotional balance.

DEAR ABBY: I'm 39 and seven months' pregnant with my husband's only child. Since becoming pregnant, I have become somewhat withdrawn due to depression. My doctor prescribed Paxil, but my husband won't allow me to take it. I don't leave the house unless I absolutely need to because he accuses me of cheating on him daily.

Two nights ago he took a single female friend out to dinner and they were gone for five hours. It hurt my feelings because in my view it was disrespectful on both their parts. When they got back, I was sitting outside and she wouldn't even come to say goodbye to me. When I asked my husband why I hadn't been invited, he said, "Neither of us wanted you there."

In his eyes he has done nothing wrong. He tells me I'm crazy and I need mental help. Am I wrong for being so upset? -- NOT CRAZY IN TEXAS

DEAR NOT CRAZY: Not at all. It appears you are married to a controlling, emotionally abusive man who may be cheating on you. One of the hallmarks of philanderers is that they will accuse the innocent partner of cheating. Feeling depressed during a pregnancy under these circumstances isn't surprising. (If you felt any other way, you wouldn't be normal.)

That your doctor would prescribe an antidepressant and your husband would "not allow" you to take it is alarming. If you have close friends and family, I urge you to tell them what's going on. And while you're at it, contact The National Domestic Violence Hotline (thehotline.org) -- the phone number is 1-800-799-7233 -- because you may need help to get safely away.

DEAR ABBY: I currently live in a situation where my husband, our two kids and I share a home with my parents, two sisters and younger brother. Sometimes it seems crowded because there is no privacy and a lack of respect.

Lately I am having a problem with my sister. Despite the fact that she and my family share the upstairs level of the home, she continues to walk around nude or in her undergarments throughout the day because she "hates" wearing clothes. At various times my family members and I have had uncomfortable encounters with her over this. I have talked to her about it repeatedly, but she refuses to cooperate.

I think it's rude, inconsiderate and inappropriate, not to mention a completely avoidable problem. What do you think? Am I wrong for being upset that her behavior doesn't change and the message doesn't seem to get through to her? -- CLOTHES-MINDED

DEAR CLOTHES-MINDED: I agree that your sister's behavior is inappropriate. She should not be parading around in a state of undress in front of your husband and children. Because she has chosen to ignore your requests, enlist the help of your parents to get the message across to her. It's their roof she's under, and perhaps they will have better luck.
