So this must be a friends with benefits arrangement that is certainly not working for you, but is for him. Sounds like he is trying to keep you on the line, so to speak, but he is not going to commit. I don't know how old you are or how long this has been going on, but, to me at least ,it doesn't seem to be to your benefit. You need to rethink exactly what you are getting and decide if it is enough. He has no more to give, at this point in time, anyway. I think I might look elsewhere. Big hug.
