N - Before my W moved out and I realized what was going on the same thing was happening to me. This was before BD and I wish I would have recognized it sooner but I didn't. Looking back I realize it was not very attractive of me to always be at home with the kids even though I thought (at the time) I was being a good parent and spouse by doing this so my W could go out with her friends. Looking back I think about what my W thought about me while I was sitting at home doing this in my sweat pants while she was out living it up, all dolled up with dudes probably hitting on her.
I agree with everyone else......make plans, get out ASAP!
