I guess I might be an oldtimer. I've been here for over 3 years and dealing with H's shinanigans for 2 months short of 5 years. What I can't answer yet is what finally happened because it is still in progress.
I don't know the label to attach to H, if it's MLC or a WAH or a guy who just fell out of love or a guy who had an EA/PA or a guy who went on secret spending sprees and shut me out of his life.
We have a lot of acres here with a very small house. H never moved out completely, but we have gone for up to 5 days at a time living together without physically seeing each while sleeping in the same house at night.
I know that it took me a very long time and many many of my own baby steps to journey back far enough to find the person I wanted to be again so I could move forward with my life.
The more I move forward and try to balance that with always leaving room for H to come with me the more positive H has responded. He is doing things again that he loves to do but gave it up for the last 4 years in his own effort to detach from me and the life we built. I have not been very successful in detaching from H or the life we built, I still love it all very much and especially with H in it.
I still don't honestly know how this will finally end, but I maintain hope that H truly is finding his way back and I will be a strong enough person to accept him when he does.
Live your life while you are still living. Riding the trail less traveled.
