Hi Luvless, Decided to stop by when you commented on our similar ages, kids, etc. on Britt's thread. I haven't had time to read your whole thread but I think I'm getting the picture.
My H and I are just starting piecing, he has ended R with OW, but it's all very new and I'm being cautious.
But, since ending this A, he has told me a lot about what was going on in his "fog" alien brain. We went through a similar cycle to the one you are describing on weekends. He told me that he would begin to anticipate on Sundays that he would be getting pressure from OW as soon as Monday came to spend as much time as possible with her. He said she would put so much pressure on him (even to the point of abuse at times) that he knows he would take it out on me.
In my DBing process, I made myself the "better option" because I didn't pressure. I set boundaries, and I was GALIng and doing 180's but I didn't pressure. Eventually, he realized I was the "better option".
I hope that helps.... Don't let him treat you badly, but otherwise "act as if"...
