What is going on in their heads?

I don't get the sense that he is regretting his decision to leave me and choose her. I think that he is taking responsibility for the fact that he took me for granted and let the OW into our lives by not realizing what he had. And maybe he is realizing that he had a great person in me and he should have cultivated that more sooner. But it's not like he is ready to change his mind. Maybe he is just trying to assuage his guilty conscience with this becasue on some level he does "care" about me (pffffff), but I guess not enough
