Sorry for causing what, man? Sorry for liking her? I dont seem to get the problem - does she not like you? Then let her be. I dont get why would she feel bad about it, and honestly, if so,then it's her problem. Maybe you dont know her that good, what kind of person she is. Maybe you should cool your head before jumping into any conclusions, mate, before taking the next step. And if she really just feels awkward about a guy hitting on her, then it's okay, but dont give her too much time to convince herself that it's wrong, that it souldn't happen, etc. Keep in touch with her like nothing happened and definetely dont mention in front of her that something did happen. And dont give her friends or your friends to much stuff to imagine and gossip, you know?
