At this point, all he wants is sex. So, that is all he considers you good for. If he was ready for something more he would go for it. Guys generally go for what they want healthy or unhealthy. It is usually pretty straightforward and there are no subtle innuendoes or feelings like in the movies. If he wanted it, he would be up for it. At this point you are hanging on cuz you can't let him go. Not the other way around. He is just getting out of you what he can for the time being. Sorry, wish it wasn't like this for you. And wish what I was saying wasn't the truth especially since your feelings are so strong. But, you have to protect and take care of yourself. You CANNOT leave it up to someone else. That will end up even more miserable and unhappy. I know because I have been there. Good luck.
You knew I was a snake when you picked me up...
