<human>: So back story, and I apologize as this is my first post.

My friend is a foreign exchange student that I met at GSA in college last year. It was a few months after she moved to town, and I thought she was cool.

Next morning I started talking to her and found out we had a lot in common, including the second language I learned a bit of in high school.

Several months of being friends, (going out, seeing movies, hanging and watching movies) and we got drunk after a party celebrating the end of that semester.  

I don't drink, and she made some crazy cocktails, and I drank twice what she did and kissed her.  She didn't talk to me for three months, and wouldn't even discuss it when we did start talking again.

So I dropped it, and time went on. We finished another semester, and then summer semester.

Her long term fiance(29f) broke up with her because she(the fiance) cheated.  So my friend was on the rebound.

I didn't make any moves, but I did offer to green card marry her because she's my friend and I give too much. (A common thing I've been told. I give until it hurts because I grew up with nothing and am decently successful for my age. I'm working on it)

We were engaged a week, and she broke it off because she didn't feel right doing it.

Fast forward another two weeks and pride comes around. I meet a cute girl and we hit it off. We started dating three weeks after to see how things are, and the new semester starts.

Since I got the new Gf my best friend won't talk to me. She's distant when I see her on campus, and she claims she just likes her alone time.

I don't know what to do. I miss my friend.

Any advice/ideas/ thoughts on what I did wrong?

Give me the gist of the text in a nutshell
<bot>: Best friend of a year that I drunk kissed once, and was engaged to for a week hasn't talked to me since I started dating my Gf.  We're all lesbians. I don't know what's going on.
