It sounds like it went well enough. Just try to keep in mind that you can't guilt him back. I sense maybe a little of that in the convo, like you were trying to make him feel bad and thought maybe that might soften his position. Here's the thing, he DOES feel bad. He feels terrible. But he feels JUSTIFIED. He thinks he's doing the right thing. He only feels bad because he knows it's hurting you, not because he feels it's the wrong course of action. So hang in there, be patient and try not to pressure him into further R talks.
