He has said that he isn't sure if he *wants* to trust me again. ie: might be easier to start something new with someone else.
I have no fears of officially dating or moving in, but the whole time he was talking about it I was focused on "what does this mean for us?"
We do have sleepovers! I spent 3 nights in a row at his place last week (I always go to his place as he lives in our hometown.) I do have some stuff there, but not enough that I don't have to pack a bag to stay over.
As for what motivates him - partly finances and I *hope* that he enjoys the time we spend together!
