I shortly went too bed after I wrote the above. I was in a bad mood and should not have let my emotions get the better of me when we talked earlier. I should have just smiled and said it will be nice to have some time to hang out with friends.
Before I suspected the EA with the OM, I would not care if W hung with friends and never played 20 questions with her. It was good until I discovered messages with a OM she was seeing at her AA meetings. She has not been back to that group in over 6 weeks and from what I can tell has not seen in him in just that long.
On one hand she tells me she wants to leave and the very next sentence is telling my how she wants to be better a mom/wife. It starts to hurt my head when I try to analyze it. I usually try to take it one day at a time and I am sorry that I am rambling.
I have reached out to other people whose opinions I value and they don't think some time apart is a bad thing. The overall theme I received was that it made the M better.
Regarding just myself I think that I handled the last weekend well without needing or asking the W for assistance with the kids. I tried to make the best of bad weekend for the kids and did not get flustered or frustrated when the W got home. I did not get mad that my plans had changed and was only concerned that my S13 was feeling better.
