At this point I'm moving on. If he wants to be with me great, if not I'll be just fine. He still wants to ML so I'm not buying that there's no connection at all between us.
By the way the book Boundaries in Marriage by Dr. Henry CLoud & Dr. John Townsend is excellent! I've only read the first three chapters and I've already learned a great deal - especially about myself. I highly recommend it. You should know that it is written from a Christian perspective.
I'm sure at some point with my own growth & development I may come to the conclusion that the marriage can't be saved. I'm not there yet. I can only control my own behavior and that's what I'm going to focus on. I let him know I'm expect to see changes in him as well. We'll see what happens...
I couldn't do the ML thing, but that's a personal decision and up to you. If it makes you feel good, then go for it. Just be careful. But everything else -- yeah, you sound like you're in a good emotional place.
