One of my exfriends boyfriend likes me but I don't he is always sending me letters but I never write back he is always telling me that he really likes me but I don't understand him: why is he with his grilfrind if he likes me? I keep asking myselfing that question and I don't talk to my exfriend so... what should I do any ideas please HELP!!

Exactly what you're doing... keep doing. Ignoring him. It doesn't matter WHY any guy you're not interested is contacting you. Don't even ask the question. Ignore them. Totally. Don't think about it at all. You went out once before, and that seems to make it more natural to think about his motives, but don't do it. Treat him like a stranger you're not interested in.

If he gets TOO pushy, confront him in front others, maybe even his girlfriend and tell him to stop flirting with you. It will embarrass him and maybe then he'll dislike you enough to stop.

I agree with beayclaire ignore hm guys are a mystery maybe because he can't have you now and he still likes you tough lol
