What does it all mean?

I just don't know what this man wants. He is so sweet when he comes home at night from work, and IDK how many times we have had sex since we broke up but it seems like every night. Yesterday, we went up to his work and he bought us dinner, told me one of his co-workers gave him props for me. He asked if i was chris' girl, and Chris said, "well, kinda." 
I don't think he even knows what he wants, I think he wants to be single and do what he wants when he wants, but I think he wants me at the same time. He doesn't want anything to change. He told me yesterday, when i was sharing my fear of not having anywhere to live, he hugged me and said that i will always have a place to stay. I know that he is stressed to, and for him to be kind like that it was really sweet. 
Part of me likes this better, but i don't like not being able to hug, kiss, cuddle, and have the right... The other night when i asked where he was i wasn't trying to sound like the girlfriend but it came out that way because i was worried about him. 
He didn't seem to mind it either. How come i trust him more when we aren't together than when we are together? Maybe its that i don't have the right to question, so i don't. But i am confident too... Why cant i be this person when i am with him vs trying to get him back... 
I feel like he is over what happened, but I don't understand why he isn't ready to be together. I FEEL like its what he wants, but then again, i don't know what the hell he wants. Its not like we have talked about things, we don't want to ruin what we are doing now, getting along, having sex, doin' our own thing, and at night is our time.... Maybe that's it? He doesn't want to ruin how good things are right now, but i want more than a roommate with benefits! I want a boyfriend, a baby daddy, and someone who i know will always be there, and i don't know that with him, I don't know that he is always going to be there, he may be talking to someone and starting something and one day out of the blue he is just going to leave and go be there for her.  this drives me fucking crazy, not knowing what the future holds, meanwhile, like last time, I am only sleeping with him, only wanting to be with him, and only paying attention to him... wonder if he is doing the same? 
I just want to know where we are headed?  What the goal is. and weather he even wants to be with me at all...
