BluWave - am hoping you will swing by again. I wanted to ask - when you were separated from WH, did you lose hope that he would come back? I recognise the behaviours your describe when he first left - I did the exact same thing and it was in my mind because I couldn't believe what was happening was really happening - I just wanted him to stop playing this ridiculous game and come home.
I am getting a lot of encouragement from a church elder who went through this 40 years ago, to stand for the marriage. She took the high road and after 2 years in the wilderness, he came back to her and they are incredibly loving now. He can't spoil her enough. She was able to do a lot more of WWJD than I ever could dream of - at one point she prayed with and for the OW. Whenever I feel like giving up she keeps on telling me to hang on , and I have been, but after Saturday when WH's behaviour was so lighthearted and indifferent... I'm super struggling with the idea of standing now. Because you need some hope to do it and I think mine is going kaputt now.
