I fingered my girlfriend? [HELP]?

My girlfriend feels guilty and has stopped talking to me after we were getting really hot and freaky on her bed and I fingered her, she got up and changed clothing and was really angry as she thinks we went too far, I tried to resolve the situation at her house, I thought I did because I left her house with a long pionate kiss, but the only time she contacted me after this ;was to check if I made it home a day later. She hasn't contacted me at all after this, I'm really upset, I even said hi yesterday via text, I got no reply, she blocked me on msn a day after the incident occurred but she's unblocked me now but still hasnt talked to me, what should I do? She's feeling guilty about it
