Yes, it may be a language of love for him. Have you read that? My ultimate 180 would be to become a more sexual partner. Kind of hard when WS is having an affair? Am I supposed to date to prove that? That seems like double cheating. But my H is in love with his OW, but I do not think he is loyal to her.
Our s*x life was fantastic, and *lack of* was never a problem. A 180 for me would be to completely go cold on him, but I have a feeling that would backfire at this point. I can see that he is really struggling and having a lot of regrets. I don't know how the dynamics will change once they both (and her kids) get settled into the new place, though.
OW will have to commute to her (40+ hour/week) job a total of 2 hours a day round-trip, PLUS her kids trying to adjust to a new school, childcare expenses, etc. -- I'm sure it will *get* to her.
