Hi, NTX! Dropped by to check on you. I'm glad to see you've had some positive interactions lately.
"I think I'll stick with my current plan to GAL and detach."
I agree 100% with this and with what JB wrote. Continue working on your personal goals, detaching and enjoy GAL. In my case, it was only when I stopped obsessing about saving my marriage and turned my focus on making myself better that things started turning around. Is this to say that will happen in all cases? No. But, it's good to know that if things don't end up working out with the marriage that YOU are a better person.
