Men who decide even after a sexual relationship with you, they just want to stay friends?

I have been completely open and honest about my feelings for this man. We have known each other for a number of years and have had a sexual relationship – hence the reason why I decided to take the plunge and be very honest about my feelings for him.
He comes up with the “I’m not capable of having a relationship, but I really don’t want to loose you as a freind as I care about you very much and you mean so much to me.”
in turn have accepted this fact this is why I thougt I would test that theory the next time we met up a few months ago (just so I wouldn’t continually get my head and my heart messed up and confused). Everything went swimmingly, I too thought he had accepted this and I was happier in myself knowing I had done the right thing in being honest and laying my cards on the table.
After a lovely dinner and a few catch up drinks at the Pub and honestly didn’t want anything. But he practically jumped on me and one thing led to another and after he even told me how special I was to him and how the reason I was, was because from the moment he met me all those years ago, he knew I was different than everyone else etc. So I wasn’t sure what to say or emotionally how to even feel as I was waiting for the back flip.
Which happened?? As a result I cut all cntact with him, not because I was angry or upset but because I just couldn’t continually feel as though I was ‘on call.’ But he kept on contacting me and reiterated about staying friends atec as I’ve already stated.
I feel as though he really does either:
1. Love me and we have something and he just wants to make sure;
2. He’s just keeping me dangling as I’m the safe bet;
3. He’s just playing games.
He’s since once again, contacted me wanting to know how I am etc the usual.
So, now I’m confused as to what is going on even though once again I have asked and stuck to mu guns.
Please anyone if you have any advice I would really appreciate it as I’m at my wits end with all of this now.
