DR. WALLACE: I'm 19, have a full-time job, but I still live at home with my mother. I pay her room and board because she doesn't have an abundance of cash so the money I give her helps pay the bills.

Two years ago, I was dating a guy I cared for, but for some reason my mother didn't like him. When I look back on it, the reason was his "shaggy dog" appearance. He had extra long hair and a shaggy beard. He also wore jeans, cowboy boots and a scroungy leather jacket. Instead of a hat, he wore a red kerchief tied around his forehead. He left town because of a run-in with the police and they told him that if he left town (he was 21) they wouldn't press charges. He did and he went to South Carolina to live with his brother.

Last week he came by my work and I almost died when I saw him. His hair was a lot shorter than it once was. Gone was the hair on his face, and also his cowboy clothes. He wore a nice shirt and neat slacks. He took me to lunch and we went out that evening. I've been out with him three times since he's been back home, and yes, the spark is still there.

Of course, my mother is not aware that I'm seeing my guy again. Since I'm 19, soon to be 20, I realize that I don't need permission from mom to date him, but I don't want to upset her. Should I continue seeing my guy without telling mom that I am, or should I tell her and possibly make her upset? — Nameless, Erie, Penn.

NAMELESS: Tell mom that your guy has returned and that she will be surprised when she sees him because the "red-neck" appearance he once had is gone and that he now has a new look and a new attitude. Have your guy and you take mom out for dinner so she can see this for herself. It is better that you inform mom about him rather than having her hear about it from an acquaintance.

LIVE-TOGETHER COUPLES COULDN'T ADJUST

DR. WALLACE: I'm 19 and my fiance is 21. We are both high school graduates, have full-time jobs and have been together for over two years. My fiance wants us to get married, but I'm not sure I'm ready to be a full-time wife. I'd like for us to live together for a year or so to make sure that we are truly compatible. My parents are divorced and my mom is with her third husband so I don't want that to happen to me.

My fiance said that he read somewhere that couples who live together before eventually getting married actually have a higher rate of divorce than couples who marry without having lived together before they got married.

Do you have any information on this subject? I don't think my fiance read the article correctly. — Nameless, Lake Charles, La.

NAMELESS: It's possible that your fiance was referring to a study conducted by the Psychology Department at the University of Nebraska. The study found that the overall divorce rate is 48 percent, but it was 58 percent among couples who lived together first. The reason, according to researchers, was that live-together-first couples simply couldn't adjust to the total commitment of marriage after living with a partial commitment during their previous arrangement.
