DEAR ABBY: For years, my wife and I were RV enthusiasts. We have a son who was envious about our lifestyle and expressed a desire to own an RV and travel the highways. When we decided to give up the practice, we gave our travel trailer to him as a gift.

The trailer has been sitting on his property for more than a year now and has never been moved. He has kept the license and insurance fees current. He recently told us he has changed his mind and is no longer interested in traveling with it. He has offered it back to us.

We have decided to sell it and wonder what, if any, moral obligation we have to share the proceeds of the sale with our son. Your thoughts? -- HOMEBOUND OUT WEST

DEAR HOMEBOUND: You gave your son the RV as a gift; he is returning it to you instead of selling it himself. While I think it would be generous of you to split the proceeds with your son, I don't think there is any moral imperative that you must.

DEAR ABBY: My wife of 17 years just told me out of the blue that she doesn't love me anymore and hasn't for some time. To say that this came as a shock is an understatement. We've had our disagreements, but we always worked through them, or so I thought.

Because she has felt this way for some time now, she has hardly shed a tear. For me, my heart is broken. I feel lost, confused, angry, depressed and I can't stop crying.

I wish I could die, but we have children and I know I can't leave them. We made a pact years ago that if we ever fell out of love we'd stay together for the kids until they were grown. Now I don't know if it was a lie or if she'll keep her promise.

I'm writing this at midnight, crying in the dark and alone. I still love her and my heart breaks every time I think about it. Please tell me what to do. -- DEVASTATED IN TEMPE, ARIZ.

DEAR DEVASTATED: I am sorry for the pain you are feeling. What you must do now is pull yourself together and find out from your wife when it was that the two of you stopped communicating honestly with each other -- because it seems your paths diverged some time ago. She owes you honest answers, and you need to hear them.

After that, you may have to decide whether you still want her to honor that long-ago promise to stay together until your children are adults. You might find it helpful to stage some of these conversations in the office of a licensed marriage and family counselor. Having a mediator present could make it easier for both of you. While I can't promise counseling will save your marriage, it may provide you with the emotional support you will need in the weeks and months ahead.

DEAR ABBY: On July 26, 2011, you posted an answer to "Jittery Future Bride in Boston." I am that woman. I had asked you how to get my boyfriend of five years to use my deceased grandmother's ring as an engagement ring.

I followed your advice and told my boyfriend-at-the-time that I wanted to use a family ring. I spoke with my father about it and checked with my sister to see if she would mind if I used it.

We got engaged seven months ago, and my now-husband told me he had been hoping to take the stone from my paternal grandmother's ring, a stone from my maternal grandmother's ring and one from his family to make a new "joining of the families" ring. We haven't made it yet, but we all look forward to the special meaning that it will embody. We even plan to make a new setting out of the old setting. It's a fairy-tale ending. -- BLUSHING BRIDE IN BOSTON

DEAR BLUSHING BRIDE: Actually, it's more like a fairy-tale beginning. I love the idea. Thank you for letting me know how things turned out. Not many of my readers take the time to do that. I wish you and your husband a lifetime of happiness together.

DEAR ABBY: The mother of a friend of mine died recently. I offered my condolences, and since then I haven't been the same.

I am nine months pregnant, and even though I should be excited and celebrating the anticipated arrival of our baby, all I can think about is that my mother is going to die one day. She's 52, healthy and happy, but I can't get it out of my mind. I have become a different person, crying at the most trivial things and often panicking that Mom's OK. I don't think I could make it through if anything happened to her.

Dwelling on this is affecting my relationship with my husband and my friends. How do I stop obsessing over this? -- ANXIOUS IN ALBUQUERQUE

DEAR ANXIOUS: A discussion with your OB/GYN would be helpful. By the last months of pregnancy, a woman's body is swimming in hormones. Those increased hormone levels have been known to have a profound effect on a woman's emotions.

The solution to your problem may be as simple as understanding that once your baby arrives and your hormones return to normal, you will be back on a more even keel. If that doesn't happen, you may have to talk with a mental health professional -- although I doubt that will be necessary. In the meantime, your mother is healthy, happy and about to be a grandmother, so dwell on the positive.

DEAR READERS: A thought for the day: The best exercise in the world is to bend down and help someone up.

DEAR ABBY: Help! My daughter just turned 13, and I need to discuss the facts of life with her. I don't know where to start.

My mom told me absolutely nothing, and I know my daughter needs to be educated in a simple but very understandable way -- especially in these times. Do you still have your booklet that gives teens answers to questions on sex? I need ideas on how to approach this. -- NERVOUS MOM IN ILLINOIS

DEAR NERVOUS MOM: Because many parents find the subject of sex embarrassing, they postpone discussing it with their children. When "the talk" finally happens, it is often too late. Their child's head is filled with information received from contemporaries, and often what they've heard is inaccurate.

Today, children are maturing years earlier than they did a generation ago. It's not unusual to hear about teens engaging in adult activities at much younger ages than teens of earlier generations. That is why it's so important for parents (and guardians) to begin discussions about alcohol, drugs and family values well before their children start experimenting. My booklet, "What Every Teen Should Know," was written to help parents break the ice and get the conversation going. It can be ordered by sending your name and address plus check or money order for $7 (U.S. funds) to Dear Abby Teen Booklet, P.O. Box 447, Mount Morris, IL 61054-0447. Shipping and handling are included in the price. You should review it before starting the discussion so you can prepare beforehand to answer questions or guide the conversation. My booklet provides answers to frequently asked questions, such as: How old must a girl be before she can get pregnant? Can she get pregnant the first time she has sex? What time of the month is a girl 100 percent safe? How old must a boy be before he can father a child?

Another important topic is how to avoid date rape and what to do if it happens. Included is information on contraception and sexually transmitted diseases (and how to recognize them). My booklet has been distributed in doctors' offices and used to promote discussion by educators and religious leaders, as well as parents like you who find it difficult to discuss these topics with their children.

DEAR ABBY: I recently started a summer job in the fitting room of a clothing store. Customers often ask me what I think about their outfits, and the most common question is, "Does this make me look fat?" How do I answer if the outfit does make the woman look fat? These women want honesty, but how do I avoid sounding rude? -- CONFLICTED IN NEW JERSEY

DEAR CONFLICTED: Try this: "The color is great on you. Let's get it in another size and it'll be perfect. Sometimes garments have been mismarked." (It's true.)
