That is all well and good, except for the part about how he is going to minimize her pain. BS. There is no way to end it with someone without hurting them (unless they want to end it too). So drawing it out is just another word for cake eating. I'm glad he wants to spend time with you and the kids, and you are having a great time doing it. But unless he really ends it and doesn't look back, you are only getting half a husband.
Again, I recommend you look into Retrouvaille. If he agrees to go there with you, they will call both of you and check to see that there are no 3rd parties involved. They will tell him he has to end it before you go. You see? You won't have to tell him, they will.
