My ex and I broke up in September. He keeps pushing me to move back in with him. I think it's too soon.?

He was very controlling and got angry very easily. Lately, he has been going to counseling and reading spiritual enlightenment books, stating he is a changed man. He wants me to state that I will be his girlfriend again but I'm insisting that it hasn't been very long at all and I need more time. He states that since I won't commit right now (in light of everything he's doing - it's only been about a month since this transformation took place), then I don't want or love him and since I want to wait a bit longer, he should sleep with others since he shouldn't be expected to wait around if I can't see he's changed. I think it's just another manipulation to get what he wants when he wants it and if the change were genuine and his love so strong, he'd be a bit more patient. Comments?
