I've been sitting next to her in one of my classes and she's been receptive and flirty -- or at least seems that way. I found out earlier today that she has a boyfriend, but she's never mentioned him to me. I got her number before the revelation today and was going to ask if she wanted to go on a date this weekend or the next... then this bombshell hit and I'm somewhat saddened. It may also be worth noting that in texts she's been distant and brief in her replies. I've never been in this predicament before, do you guys have any advice? Think I was led on and should just drop it? Think there's a chance and I should go for it anyway?

If by "pursue" you mean you like to date her, wouldn't be a good idea. If she has a boyfriend and she's flirting with you, she probably isn't loyal. Those of the kind of girls you avoid or hit it and quit it.

If her texts are distant and brief that should tell you something. Your texts are probably really involved and she probably wants to squash any feelings that you might have for her because she probably feels that you like her. Just because a girl gives you her phone number doesn't mean that she likes you. She probably just wants to be friends seeing as how she already has a boyfriend. Just go searching for a single girl....there are plenty out there.

hit it

Leave her alone. You won't trust her because of you can take her from her man, somebody can take her from you.

Save her from that lame boyfriend she has..

aka hit it

Its great we all have the same advice.. Really helping the op.. Next time we need a pre-thread before giving advice

Yeah, pre-threads are key.

Next time come to us before making any life decisions. 

Is the girl your age? ~20? Probably had this boyfriend from highschool and is now looking for something different.. A lot of couples grow in different directions at that age.. Nothing wrong if she's looking around.. Nothing wrong if you are the guy she's looking at
