Your wife says she wants to work on the marriage, you say you are standing, she is scared and you are dating.
Do you realize that HER crisis is not a marriage issue?
It may look like a marriage issue, but it really is just HER having a crisis.
She is unable to magically come out of the crisis just because you go to a program, or you start dating. She is still in her crisis. Kind of like if you had cancer, you dont just magically get healed.
If she was sick with cancer would you be dating? She might be unable to perform her marital duties if she was sick with cancer. You need to heal, she needs to heal. That takes TIME. LOTS more TIME than most people are willing to give.
But if you look at it in the scheme of how long your marriage is, maybe it is a very short TIME. If you are married 50 or 60 years, 5-7 years is pretty short.
