Dont understand what ive done wrong here?

I think that you need to talk to her and tell her how you feel like "i really like you and i don't want this to come between us" or something like that. Apologise and grovel until she speaks to you again, and then try and find out what you did wrong. Don't confront her angrily, but be kind and patient, and I'm sure everything will work out in the end :)
