MIL came to dinner. W, thankfully, did not. I did not bring up W at all, but I got a decent laugh because MIL did bring her up, mostly to complain about her. I didn't say much in response to that.
I talked to my mother about the advice to minimize interaction with MIL. FWIW, she agrees that MIL will always have W's interests at heart, but she sees no harm in MIL coming for dinner. She suggested that I stop inviting, and let her ask to come by, so that's what I'm going to do.
Today was a good day. Work went well, in a GOOD mood all day. Tomorrow night will be hard, D is going to W after school because school is closed on Friday. W will actually have her more this week than I will, which is a first.
Still thinking about everything you guys said above. Kaizen... I think, yes, I would still have MIL at the house if I were dating someone else. Mach, I don't think I would skip some activity to facilitate that relationship.
