You are in a tough spot and I feel for you. The absolute best thing you can do is to continue to work on GAL. I too have read the 5 love languages and fortunately I am still in a position to use some of that advice. I am not 100% sure what my wifes LL is but I am leaning strongly towards Affirming words. Her OM (it's ended according to her) made her "feel smart". My counselor said that he "validated" her. My wife has a ton a resentment built up towards me so she brushes of the compliments etc. but I am hoping in time she starts to believe them.
I read a book called "Wild at Heart" by John Elderedge. It is an excellent book built on this premise. Every man needs 3 things. 1. An Adventure 2. A Battle 3. A Beauty to rescue. I suspect that by reading your post that some of these desires are being fullfilled in your H.
The book also points out that men like to control most situations in their life (we should live the adventure instead of trying to control it). I guess my point is that I suspect once your H injects enough control into his current situation the glamour may wear off. It sounds crazy but I think we can all atest to the fact that we are our own worst enemies by bringing on our own misery.
