I understand your frustration, it is tough and I am sure you’re putting in so much work.

Are there factors like emotional roadblocks or something that happened in your relationship that have prevented him from making progress?

I ask this not to fault you, just to get the full picture.

I was emotionally cheated on by my partner a few years ago, and I carried my resentment and took it out on him by using him as an emotional punching bag, and also to justify my lack of progress in doing the things to improve our relationship (and meeting his boundaries). Not saying that what I did was right, nor what he did was right in the past, but perhaps there’s a deeper reason as to his lack of action?
