Hmmm, well, first you have to decide if he's telling you the truth. I'm sorry it sounds harsh, but he's obviously no stranger to lying to get what he wants. He stayed in that relationship for a long time while reassuring you that he was going to end it. Is there another way you can verify the truth of this? But that just brings up the issue everyone has been talking about. He is not very trustworthy. Not to sound cliche, but whether or not he might do the same thing to you is a valid concern. If you decided to date him, trust would be an issue right from the very beginning and that's not healthy at all. The first parts of a relationship should be the whirlwind romantic parts and I don't think you'd have that with him after all this.

Ideally, I would tell you that you should not even bother with this guy. It sounds like carrying on a relationship with him would only bring you more emotional turmoil and pain. But, if you really want to be with him, you definitely need to at least take some time before you jump into a relationship with him. If he truly wants to be with you, then he'll wait for you. There's always the possibility that he could just use you as a rebound, which would only break your heart.

Whatever you decide to do, we'll all be here for you at PC regardless!
