I do not know anything about the religious aspect, being an atheist, but I can tell you that what is doing, in general, is not nice. Nice people do not do that. But then again perhaps the religious baggage and prejudices make him torn at this point. Do not know about that. But still, not nice and unappreciative. I do not think it is productive for you to regret anything at this point, but you have learned that you do care very much about how the sexual partner behaves after sex. You do not want to be ignored. You want to be valued and appreciated.

It sure hurt to get this knowledge, but you did get it. So now you will be able to choose future partners with that knowledge in mind: you will select guys who are nice and appreciative. To the extent that it can be predicted in advance!

You did write "I know he's a really nice guy" but his behavior, so far, says the opposite.
