So I'm in college at an all girls school which majority of the girls are gay, bi or bi-curious and I have a crush on a girl that never told me her sexual orientation. She knows I like her but all she told me was that she was talking to someone. I hear things about her that she's atright, she has a boyfriend and that she's bi stuff like that but none of that came out of her mouth it was always what I had heard from someone. I've grown a really strong crush on her and I know she knows it. When we talk she always seems to flirt with me and I like it of course. There was a point in time where she basically made me choose between her and my ex and left me alone to choose and I chose her. Then there was a time where she called me on my room phone for something to drink when she has more friends in the dorm that has more drinks then me but she calls me anyway. I feel like that was a way to get me to come talk to her or for her to come to me for some reason, I don't know. And she told me if I don't say hi to her everyday she's going to punch me (in a joking way), she knows I'm shy and every time I see her I get nervous and try to avoid her, and she notices it. So my question is what should I do? And the little things she's doing what does that mean?
