What does my ex wnat with me? I have two children, neither of which are his. I have nothing to offer him.?

I have no time for anything or anyone right now and my ex wants to be here as a friend or boyfriend. He wants to really be with me and says that I deserve to be loved so he wants to me to trust him to do so. By the way what do forehead kisses mean and when a guy playes in your hair? He does this a lot.
