Hey guys,
I am a college student and the past couple weeks i met this amazing girl. She is so cute and sweet and i really like her. She is a part of the group i hang out with and every time we go out a can't stop feeling attraction for her and flirting with her. But the thing is he has a BF.
I DHV for the first day until now and i think she likes me too. She smile at me and she IOI me. I heard her complying that her BF doesn't talk to her in a sweet way. I think a have a chance with her but i don't know how to show her in a more direct way that i like her.
3 days ago i should had inform her about something in school so i send her on FB that i have something to tell her. I didn't told her what is it and she din't ask. I told her to meet me and she came. She come with a friend and while i was showing this thing in the computer (in the library) we flirt. Before she live, i told her that i am going to a club with the guys and she told me she is coming too. But she didn't.

I need advice what to do now. I am thinking about sending a msg like :
Me:<congratulation>
She:<for what?>
me< i just caught myself thinking about you>

Or tell her straight that i like her and i know she has a BF but i would like her going for a Coffee with me. And tell her that i want try anything on her.

What you guys think?? I really like this girl (I didnt REALLY like a girl in a long time) and i want her to be my GF!

P.S i even stop seeing a girl i was f**** so that i can be with her!
