Dear Margo: I've known my girlfriend for about two years, but we've been dating for six months. We met a while back, went on a few dates, and then I moved to another city for a year. I'm back in the city now, and we're pretty serious.

Here's my dilemma. About three weeks ago, during sex, the condom broke. We have been using condoms as protection because she doesn't tolerate birth control pills well. The next day, she took Plan B, so we're hoping we're in the clear.

The thing that came out during the course of all this is that we feel differently about abortion. I'm pro-choice, and she's pro-life. Basically, the whole event has made me nervous and gun shy about sex in general....
