<human>: So me (19M) and one of my best friends(18F) who we will call M, are both going to the same college. She lives in the dorms but I got into an apartment. 

While she's been at the dorms she has met these new girls and started bringing then over to the apartment on weekends to drink and hang out. Lately me and her new friend (18F) who we will call A, have been hanging out and "talking" for a while, about three weeks now, and even give out about twice and hung out quite a few times. Everyone knows we are getting close and they are all sure and excited that we are going to get into an actual relationship and every thing except im not sure what I really want. 

Back to M the best friend, I have always had feeling for her. I just never pursued because her type is actually the douche bag type. Not even joking, she goes after wavy haired guys that are literally douche bags to girls and I'm not the only one to tell her this. 

Anyways lately as ive been talking to A, my feelings for M have been growing and growing. I really like her and I don't know what to do because she's one of my best friends but im talking to her best friend.

Anyone have any idea what I should do?

Can you succinctly summarize the text in 1-3 sentences?
