Frank, I'll reply more in depth to your post later.
I need to say what I found out this morning after my conversation yesterday with W. She told me that she is as protective of our children as I am. Her text messaging to me last night stopped suddenly and I had a strong feeling that OM was over again last night. I had the children with me so I couldn't verify that.
This morning, on my way to dropping off D6 at school I went to school and OM's car was parked out front and W was pulling out of the garage. We didn't talk, but she did call me to ask me how I am doing and to ask a favor. I told her I am doing great and told her no on the favor. She then called MIL and told MIL that I treated her rudely in telling her I would not do her a favor.
My guess is that W did not tell MIL that OM was over again last night. W is setting such nice boundaries in her new love life. Lie to me, cheat on me, make no changes and I'll take you back into my life and my bed. Nice. She is certainly NOT the woman I thought I married. Sad.
