DEAR ABBY: My twin sister and I were raised by a single mom. Because Mom received welfare benefits, she was required to list "potential" fathers in order to receive aid. After a time, the state required paternity tests be given to the men she had listed, so we had no idea who our biological father was until we were 16.

Although paternity was proven, he never attempted to contact us. I recently learned that he died several years ago at a relatively young age (mid-50s). I also discovered that he had at least two other children, one of whom I was able to locate on Facebook.

I don't want to cause any undue distress by reaching out to them. However, I'm curious about any historical information they could provide, particularly medical or hereditary issues I should know about. All of a sudden I have this overwhelming need for information, especially now that I have a child.

Should I try and contact my half-siblings, or let it go and hope there's nothing there to find out? I don't want to hurt anyone, but I feel I just have to know. -- NEEDS TO KNOW

DEAR NEEDS TO KNOW: The revelation that you and your sister exist may come as a shock to your half-siblings, so be prepared. Ideally, the way to go about asking for the information you're seeking would be through an intermediary such as a lawyer. However, if you can't afford one, then write a letter explaining who you are and that you are a parent and would like any information that can be provided about any genetic illnesses that run in your father's side of the family, including his cause of death. While you're at it, be sure to mention that you are not trying to intrude -- only to find information that may be pertinent to you, your twin sister and your child.

DEAR ABBY: I have been separated from my ex-wife for a year and I'm still depressed. I can't eat, I sleep only a couple of hours a night and since the split I have lost 40 pounds.

I'm in my late 20s. My wife and I were together since high school. We have two kids. We separated because of her infidelity and immaturity. I was the one who decided to leave and I don't regret my decision, but a part of me can't move on.

I'm still nice to her and cater to her sometimes, but I want to stop. I feel she uses me because she knows I will always love her. How do I break my bond with her? -- STILL NOT OVER HER IN NORTH CAROLINA

DEAR STILL NOT OVER HER: If your ex-wife is the only woman you have ever dated or been intimate with, it's not surprising that this has been extremely hard for you. Divorce can bring with it a roller coaster of emotions, some high and some low.

Because you can't seem to break out of the lows, it might help you to go online and research divorce support groups for men and attend some meetings. However, if you find you need more help than that to disengage -- and you may -- ask your doctor for a referral to a licensed mental health professional.

DEAR ABBY: I am a 70-year-old woman, married for 50 years, and I hate my husband. He wants to go to swinger parties and toss me to other men. I tried it a couple of times for him and hated it.

He is overbearing and rude. We don't have any friends where we live, so he seeks out new people. He doesn't listen to my begging not to do this. His computer is full of porn and his thoughts are sinful, although he can't perform.

Every day I wish he were dead, but I feel guilty for these thoughts. Please tell me what to do. My life is unbearable. -- PAST MY LIMIT IN ORLANDO

DEAR PAST YOUR LIMIT: By now it should be apparent to you that you can't change your husband. The only thing you can change is yourself. If you find the strength to do that, your circumstances will change. Because you say your life is unbearable, stop bearing it. Talk to a lawyer and set yourself free.

DEAR ABBY: My 33-year-old son has mental problems. He is moving out to live with a guy he has been talking to on the internet and who has met him once.

His father and I are against it, not because of their homosexuality but because we are afraid it's a dangerous situation. We have learned that the guy was arrested three years ago on three different charges. He says he was cleared, but refuses any background checks or fingerprinting for jobs and/or government housing.

When we tried to talk to our son and explain the dangers, he became irate and blamed everything on us. He has no driver's license and has threatened to take off. He has also threatened suicide. We have asked him to consider talking to a psychiatrist, but he refuses. He does see a psychologist every three months, and he's supposed to be on medication, which he refuses to take. How can we deal with this? His psychologist won't talk to us unless my son gives the OK. -- DESPERATE WORRIED MOTHER

DEAR DESPERATE: Because your son is an adult, unless he is a danger to himself or others, there is nothing you can do to prevent him from leaving. However, you can write his psychologist a letter letting him/her know what is going on and address your concerns. There is a chance your son might pay more attention to what his therapist says than to you.

An organization that may be of help to you is The National Alliance on Mental Illness, accessible at nami.org. It may be able to provide you with the guidance and emotional support you need.

DEAR ABBY: I'm 16, and I have a crush on a guy who is 23. We met in the gym he works at. He's very shy and he didn't make the first move, but now we flirt a lot. I don't know what to think because we met at his work, and he's so much older than I am. What do you think about the situation? If he kisses me, what should I think? If he doesn't make a move, what should I do? -- CONFUSED IN CONNECTICUT

DEAR CONFUSED: My advice is to forget about it. If he kisses you, consider the consequences if your parents found out what's been going on. It could cost this man his job. He may be very nice, but he is so much older and more experienced than you are that there could be criminal penalties and possibly jail time for him if he's foolish enough to pursue you.

DEAR ABBY: I recently realized that my mother-in-law stole several of my prized possessions. It seems that my husband's brothers, who helped us move when we lost our home, took the items (obviously at her request and with her approval) instead of placing them in the storage unit as instructed.

I am furious at her and my husband's brothers. How should I deal with this? I want to confront her and let her know that I am aware of her betrayal, but my husband is a great man, and I hate to hurt him in this process.

When I told him I was aware that his mother had stolen from us, he said he would make it up to me and that his mother is old (she's 81) and I should let it go. However, every time I visit her home and see my things it hurts. How should I deal with this? I feel raped. -- FURIOUS IN TENNESSEE

DEAR FURIOUS: If the items are replaceable, let your husband do as he promised. If they are heirlooms, you will either have to wait until she dies to reclaim them or go over there and demand that she give them back.

DEAR ABBY: I recently went to a funeral viewing for a friend's adult child whom I had never met. After entering the funeral home, I saw a computer-generated sign stating, "Please understand that we (mom, dad, brother and daughter) just couldn't be here."

Abby, I wasn't there to see the deceased; I was there to express my sympathy to the family. Why bother to have a viewing? All I wanted to say was how sorry I am for their loss. -- KAREN IN PENNSYLVANIA

DEAR KAREN: Please have a little less judgment and a little more compassion. Remember that not everyone deals with death in the same way. The viewing was for family members, friends and acquaintances of the deceased who COULD bear to be there. You can still express your sympathy to the grieving family by writing them a condolence letter.
