We find it disgusting and appalling that he comes over for Christmas Eve dinner, goes back and sleeps with ow, then comes back the next day for Christmas dinner and he comes over fairly late in the day, like about 4PM.
I couldn't do that. When xH and I were still living in the same house, I didn't let him come sleep here when he was out at bars (with his OW). He slept in his car many nights. Oh well. I wasn't his 'resting' spot between parties.
Why do you keep so much bottled up? I sometimes worry you don't value yourself enough to realize your opinion, your feelings (especially your hurt feelings) matter so much.
