Wow did you see me make assumptions or what! Ok well if OW is still in the pic and he didn't mention restoring the marriage, it may be that he just wants a clean slate and forgiveness from you to feel good about his new start. The baptism is probably part of that. But if you've not been on a track to forgive, you can't just "give" this to him "like that."
My sitch is WAY new compared to yours, but with my divorce being finalized any day now (the court has all the paperwork and is ready to decide on the basis of the papers filed) my H in the past few days came at me with the whole "I'm so sorry" and "I hope you can forgive me." I think he's feeling really emotional about all of this and wants the guilt to stop, and he is asking for my help. I mean, I said what was in my heart, but I can't fix this for him.
I guess listening to him if he wants to talk is the best thing for you, but if OW is still in the pic, I'd be very careful about how much you "let him in" to your life because you are bound to get hurt if you still have feelings and if he is still with her.
