What would be your opinion of him/us???what do i do?

I think it's best if you both see other people. Having a relationship with him doesn't seem like it's going to do you any good in the future. If he's off with some other girl then you should do the same and find someone else. It's only going to get you hurt you if you continue to try. I'm sorry and I hope in time that you'll find someone truly amazing.
