I love to hear from you; thank you for posting. I'm sorry your H is still chasing his tail and making you crazy. I fully understand that. I am happy he agreed to see a C though, and that you will support him thru this time. Good for you. Maybe and hopefully, things are going to start turning around.
I don't know what makes my H unable to tell me that he doesn't see us together anymore. It may just be a passive-aggressive trait. He can't even commit to NOT commiting. Who knows? I surely don't.
What I see happening is him resigning himself to the mistake he made and having to live the rest of his life with it...but not with me.
Most of us really marry only once. First love endures, even unto our dying day. And we never really divorce.
