After all that you are still holding on to this man? Blue, get the duster out and dust yourself off. Don't hold on anymore, let it all go. You deserve so much more.
In the grand scheme of things it doesn't matter what he is or is not doing now. He will do what he does for whatever reasons he generates in his mind.
Agreed. Focusing on what he is doing with the gf isn't helping you. Reason being, it's keeping you stuck. Initially, he won't be the same as he was with you. He is mirroring someone different now, so of course his demeanor is different. Only time will tell as to how things end up. But, by that time, I do hope you are long gone, living a wonderful life and looking after you
