Why doesn’t he want to get physical with me?

So I’m dating a guy. He is wanting to be a pastor one day, and he’s getting life back on track for God. I totally respect that. However, tonight when we hung out, he told me that cuddling the other night “did things” to him and it was too far. He told me he’s wanting to wait awhile before kissing so he doesn’t take a part of myself. This is the same guy that had said all those things in my previous questions. He mentioned tonight that he wants to change my last name so I know he likes me. He says that if God isn’t in the center of a relationship, there’s no reason to move forward. I was a little offended, not going to lie when he didn’t want to cuddle. I’m very confused because I thought he really liked me. Why doesn’t he want to get physical with me much?
