Do I want him?

I broke up with my ex about 2 months ago because I found out he liked another girl. But he liked her less than me and he was going to stay with me , but I over exaggerated the situation and dumped him. When he was going out with her he accidentally kissed another girl but that has never happened again. I have never been able to get him off my mind. I love him so much. He still likes me and yesterday we kissed, and neither of us felt guilty. However, he says that even though he loves me, he wants to stay with her. But he also said that at the moment he wants me more, but is going to stay with her. I am also friends with her, and she is getting bored of him and is considering breaking up. Thing is if they do break up I dont know wether I would want him because of all that stuff. I really like him and want nothing more than to be with him, so I’m so confused. Also he’s not the kind of guy to mess me around, he just tells me what he feels and thats it. Someone help please.
