You do deserve better!!! He is a total cake-eater! Don't let him talk you into anything you don't want to do.
I think you are the strongest person I know. To go through 3 years of this; that is unbelievably strong and brave! You have done everything you could; I agree with Yoyo, it takes two people eventually to make a M.
I also agree that no longer having to walk on eggshells is a relief. The peace and serenity I feel now is something I didn't have for a long time. I was sad and such low PMA for so long; I felt better and stronger after getting separated and more so as time goes on. I think that is probably true for many of us.
I don't have much advice to offer, but you have all my support!!! ((((((Joie)))))))
