I've never really tried with a girl that is 'seeing someone' but I want this girl and I know I can get her. So I ask her to dinner and she says she wouldn't want this guy to get the wrong impression. Of course I pulled the classic
"woahh I'm just trying to get to know you better I didn't know you were talking about a date". After this she offers to have coffee with me sometime at school. This girl is my lab partner so everyday in class we sit next to each other and talk for an hour and a half. I haven't gotten the general type of ioi's you would get but I just have that guy feeling I can get with her (I mean hook up not date) because I don't really see this 'guy' as a big obstacle.

I wanna know anything and everything you guys have to know about getting with a girl that's seeing another guy. Feel free to comment anything I'm open to everything.

Btw I was thinking about using the boyfriend destroyer but we'll see.
