My crush completely ignored me?

[Personal Question]

Me and my crush are good friends, but in the past few days it seems like i did something thats making her avoid me. We live near each other at university and we always say hi and talk for a while about things. I never made a move on her because shes a different religion and I dont believe in 1 night stands or just "hooking up". Ive realized deep down that thats why i didnt hook up in high school. I didnt believe in just hooking up for the sake of hooking up. Anyways, so on Friday I was really hammered and we kept texting each other where we were and then when id get there I would just sit (in a group)... The next day I texted her asking her what i did last night and said i was trying to piece it together... Then i asked if i was being an idiot.... Stupid question, I know... So I saw her and her friend laughing or giggling at the text about 10 minutes later at the cafeteria and when they saw me walk into to room they got kind of quiet and just smiled at me and she said she got the message. She told me that i didnt really do anything and then she talked to other people in the group for the rest of the time...They were clearly talking about me beforehand
So today i decided to like one of her recent facebook photos and then when i saw her later, she just walked by with her/my friend (a guy) and made it like i wasnt there....

I cant figure out what I did wrong, but I still want to be friends with her
How can I just be friends with her again if she seems to be drifting away? Is there something I can do or just pretend that I dont notice her slowly casting me off? Her friends dont talk to me
