Hmm, this doesn't mean that she doesn't still adore you. There might be some things that you like to do that you feel other people you know might enjoy more then she would and it would be better if they go along rather than her. Doesn't mean she's starting to go off you or anything (I assume) but also at the same time.....the event space will be vast what the hell is her problem why can't you go?
Ask her directly what is going on i'm feeling left out? anything you wana tell me biatch?
