it's entirely possible that all this is is infatuation. however, it's possible it's not. if she really does love you then she'll leave her boyfriend soon enough so long as you put some pressure on her to do so. personally, i wouldn't be so blunt as to say "make a choice: me or him" because that could really put her off. but occasionally bringing up the fact that you really care about her and want to be with, can only do you good. to summarize, just put some subtle pressure on her to leave the other guy and continue doing what you're doing.
