if i were you, i'll leave the guy... if he comes back to you (being single again), then that's the right time to start your own relationship with him... from the above quote, it shows he's somewhat selfish in a relationship... from the start, he's cheating! If he coudnt loose u, then he should leave his ex!!!
Frankly, I don't buy that he's not a cheater. He's in one relationship, telling you that he wants a relationship with you... That's emotional betrayal. What is cheating if not betrayal? Sounds like a good one to run far, far away from. Unless, of course, you like the thought of him telling his current gf all the same things he's telling you (about wanting to be together, couldn't lose her)... Or, better yet, being out in the open dating you, while having another "mate" on the side, telling her all the things he's now telling you (about how unsatisfying his current relationship is, how he really wants to be with her)...
Sorry, you can't have your cake and eat it too... You don't know what he's telling this girl...and I agree with dawn...he's an emotional cheater. And how, exactly, is one supposed to sort things out in one's head in a relationship??? I'd get out of that situation, FAST
ditto - drop all contact with this user. He is a liar and a cheater, and will always be one until he has a good reason to stop. If you meant anything to him, he wouldn't have kept your relationship a secret, nor would he have run back to the ex the first time she gave him half a chance.
Physically cheating, well maybe not but he has definately crossed some lines. If you were with him would you be comfortable with him having the same kind of relationship with someone else? I doubt it. I would move on quick.
