If this guy really does love you, then why is he still with this other girl? You should find a real man who's not afraid to be with the one he loves. it may hurt, but can you imagine being with this guy, like the other girl currently is, and then having him tell someone else that he loves her, even though he's with you? Tell him how you really feel about him, if he breaks it with the other girl, then great, the best to you. However, if he keeps stringing this thing along, lose him, he's not good enough for you. I understand that it would be hard, since you have feelings for him, but from what you've said, it sounds like he's not worth it.
