DEAR ABBY: Is 16 too young to know you're truly in love? My boyfriend, "Miles," and I both feel that we're truly in love and want to spend the rest of our lives together. We realize that it will be a few years at the least before we can marry, but we're willing to wait.

My older sister laughs at me when I say that I know I'm in love. She says I am way too young, and I need to be older and more mature -- like she is -- to understand. She's 17 1/2, so she's really not that much older.

I have a large picture of Miles in our room, and when she has friends over, she points at it and says, "That's Judy's true love forever," and they all laugh about it. Can you be truly in love at my age? -- JUDY IN BIRMINGHAM, ALA.

DEAR JUDY: Yes, it is possible to be truly in love at 16. However, at 16 you are still maturing emotionally and intellectually.

The problem with making a lifetime commitment at this age -- although some people have done it -- is that both of you are still "growing" as individuals. Not all people grow at the same rate, and their interests often diverge. Does this mean the couple is not truly in love? No. But it does mean that it's better to be older before making a promise to stay with someone "forever."

That said, your sister is wrong to belittle and ridicule your feelings. And for her to do so is a reflection of her own immaturity.

DEAR ABBY: I have been seeing a certain man for about eight months. We get along wonderfully most of the time. However, when we're out in public, he is very cold to me and standoffish.

Four months ago, we were at a trade show where he ran into friends of his and stood and talked for 15 minutes without ever introducing me. I finally walked off.

The same thing happened again on Mother's Day. Some friends of his approached, and they visited awhile. The difference this time was one of the men in the group noticed me standing there and interrupted the conversation to introduce himself, as did everyone else then. My so-called boyfriend never said a word.

As we were leaving, the main speaker at the clinic where we were stopped him and asked, "Is this your wife?" -- which I am not, but I also am not as he introduced me. He replied, "No, this is my friend." (We are intimate!)

I do not like the way my boyfriend treats me in public, and I am tired of his being noncommittal. Am I being unreasonable? -- TIRED IN COMANCHE, TEXAS

DEAR TIRED: Your "boyfriend" either was never taught good manners, or he is so into himself that he has no concern for your feelings. Instead of pretending you were part of the pattern on the wallpaper and ignoring your presence, he should have immediately introduced you.

What happened at the clinic should be your wake-up call. Although you are intimate and consider him to be your "boyfriend," he has stated publicly that he considers you only a friend. (With benefits!) If that's how you wish to be regarded, then continue seeing him. If not, give your ego an enormous boost and walk away. He's obviously still looking, and so should you.

DEAR ABBY: My husband, "Sean," died suddenly last year. He was a wonderful husband and father in every way. I knew about Sean's cross-dressing from the beginning and accepted it unconditionally.

Our 11-year-old son, "Brad," knows nothing about this part of his father's life. Sean and I discussed it many times, and it was his wish that Brad not be told until he was older.

My concern is, I receive mail, credit card applications, personal letters, etc. addressed to "Serena." Only one member of Sean's family knows about Serena, although most of his friends do. I am unsure what to do if and when Brad asks questions, as we all know he will.

There are also clothes to get rid of and other personal items of Serena's.

I want to honor the memory of my husband and his other self without hurting his family or our son. It is hard sharing this information with banks, credit card companies, and other places where "her" name appears. I try to explain that Serena was Sean's alter-ego and that when he died, so did she, but I do not want to go into detail.

How do I honor the man and woman I loved, and at the same time, protect our son? This is the only subject we never had a chance to talk about. -- ALONE WITH THE SECRET IN WISCONSIN

DEAR ALONE: Please accept my deepest sympathy for the loss of your husband. When dealing with credit card companies, banks, etc. it is not necessary to go into detail about who Serena was. It is none of their business. Simply state that your husband, Sean, is deceased, and mail in his name should be stopped. And also do the same for Serena.

As to discussing your husband's other self with your son, my experts advise that the best time to let children know about the cross-dressing is when they are very young (3 or 4), and can accept it naturally as "the way things are." Eleven years old is too advanced an age for the subject to be introduced now. You would be better to wait until the boy has matured into his late teens or adulthood to discuss it with him.

When you dispose of Serena's things, do it at a time when your son is away or out of the house. If there are special items you would like to hold onto as keepsakes, consider renting storage space or putting them in a location in your home to which your son does not have access.

DEAR ABBY: My daughter and I have been busy addressing her graduation announcements. We came across a problem we thought you might know the answer to. How do you address a formal announcement to a married couple where the woman is a physician and the man is not? "Mr. and Mrs. Joe Smith" is obviously not right, but I'm not sure "Mr. and Dr. Joe Smith" is correct, either. Can you help? -- NEEDS TO KNOW FAST IN ST. LOUIS

DEAR ABBY: I am 27 and thinking about the future. After much consideration, I have decided that unless I have a very strong relationship in place by the time I am 30, I plan on going to a sperm bank and having a child on my own.

With the divorce rates what they are, and the custody disputes I have seen my friends go through, the idea of having a child on my own is very appealing.

I have set the deadline at 30 because I want to be a younger mother, and I desperately want my father to be around for my future child.

I felt good about this decision until I discussed it with a close friend who called me selfish for consciously depriving a child of a father. I think it would be selfish to deprive my future children of their grandfather, who I already know is an amazing person.

What do you think about this? Am I being selfish? -- SECOND-GUESSING MYSELF IN NEW YORK

DEAR SECOND-GUESSING: Although many children are not so fortunate, I think that "ideally" a child should have two parents. Had you told me that you felt you wanted to become a mother by age 30 because you felt your chances of delivering a healthy baby were better, or that you felt a child would complete you, I would be more inclined to support your decision.

However, having a child because you want your father to be around does not strike me as a justifiable reason, and I hope you will think longer and harder about it before signing on for single motherhood.

Have you discussed it with your father? At the risk of sounding negative, what if he were to pass away or decide he'd like to move to Florida? Then what?

DEAR ABBY: I am a pack rat and a slob. My husband is the opposite. I am trying hard to change my ways, but it is not easy because I was raised to appreciate sentimental gifts, and my husband is always saying, "If you don't use it -- toss it!"

It has been especially difficult because we now have a 3-year-old. He gets many gifts from my mother. When he outgrows these toys, I often throw them out or give them away. If it's something Mother has purchased, I am afraid she may find it in our garbage and make me feel guilty "because it cost a lot of money" until I reluctantly agree to keep it.

This has happened in the past, and I have suggested that my mother keep it at her house if it means that much to her. She says her house is much smaller than mine, and she doesn't have the room.

Any suggestions on how to stand up to her regarding these toys? I feel constantly railroaded when it comes to getting rid of anything in my house. -- PACK RAT IN REHAB

DEAR PACK RAT: You may think you have a problem, but it pales in comparison to the one your mother must have if she's rifling through your garbage. The next time she brings something you have thrown out back to you, confront her on that. Then remind her that regardless of how expensive the item may have been, once a child has tired of it -- it's over. And if she persists in laying on the guilt, donate the item.

DEAR ABBY: I'm slightly confused. If someone has extremely good qualities and states what they are, is that bragging -- even if there was no intention of making others feel bad? -- INQUISITIVE IN SUNNYVALE, CALIF.

DEAR INQUISITIVE: It's a matter of degree. Tooting one's own horn isn't necessarily bragging; it can be a form of self-promotion. However, if you go on and on about your own "extremely good qualities" and fail to mention the good qualities of others, frankly, you will eventually find yourself talking only to yourself.
