Does he even want me??

We were together, for a year, but we broke up. 
And now, we're kinda trying again. 
I want to be in a relationship with him again so bad, and he says he does too, but he's not sure if we should yet. 
He's hiding me from his friends and family, like he won't tell anyone that we're trying again. He says its cause he doesn't want anyone to get their hopes up and then we break up again. 
He won't take me on dates, or let us sleep together again (like during the nights) he says it'll happen soon, but he cancels every plan we make to have a sleepover. 
When we see each other he'll only see me for like a maximum of 3 hours before dropping me off again. 
He tells me he loves me, and he shows it too, and we still have sex. And we talk everyday again, texting all the time, and on the phone every night for a few hours. 
But it's like it's not progressing, I feel like he's hiding me, and doesn't want to be with me, but just entertaining me for whatever reason. 
What are your thoughts on this?
