Your H's lack of response is actually telling. I would submit that suggests he DOES care. He's just closing off so much, to not show his emotions.
If he did not care (the opposite of love is actually ambivalence, not hate), he would have been happy for you and likely would have responded that way.
I don't remember if you spoke directly to this, and since you are here, I'm guessing that the A is NOT a deal breaker, for you. Even though you have boundaries (your moving out) around it.
That said, yes. Keep working on you, your GAL...
I understand that you don't know what "went wrong" in the M. Your H won't tell you what his complaints are. While some WAS will happily offer the LBS all their complaints... including some that are completely made up and untrue... others get absolutely no feedback. I was one of those. I could only guess.
So what do you THINK your H's complaints might be?
After you make your list, take a close look and see which ones would be truly valid.
Remember, an LBS is GREAT at making things up in their own minds, taking ownership of ALL the problems in the M. You really need to take a close look at what you feel are valid, that you WANT to change, even if your M is not saved. Problems you could work on that would help ANY R or future M.
And having done that, how would you go about making these changes in yourself?
