Huge problem!?!?!?!?! my bestfriends pregnant!?!?!?!?!?

okay,so thanks for reading this in advance&i really hope you can help me i have no idea how to handle this. so i'm gay,18 year old guy,and somehow i had with my bestfriend. and she's a girl. i'm still gay,i've tried to master my bate with "straight guy"mags and my kite did nottt stay airborne lol. but when i did it with her,it was great. probably the best i've had so far. and i've just now realized it but i think i've had a "straight crush"on her for a while now.idk,that thought's still new to me. but my problem's not that i'm confused with that or anything,we're cool with that. and she's still my bestfriend,this happened a while ago,back in may when we got outta school. my problem is that,sunday night when we were hanging out she told me she was pregnant. i said "cool." then she got out my car and went inside her house (she told me right after we were hanging out all day when i was dropping her off). and i haven't talked to her since,i ignored her calls and texts all day today,i just didnt know what to say. we only did it once,and without a condom,cause i wasnt planning on having with her... and it was in may,so she's near 12 weeks im guessing,so that's too late for a smhsmhortion i think. i just dont know how to deal with this. i'm only 18,i live upstate but i wanted to go to college in the fall in the city,what should i do? should i not go to college?marry my straight baby-mama even though i'm gay? WTF,please help me! :(
