wife hardends heart-2

[planet]

With W being angry and annoyed with me all the time drains me.
The 'not quite OM' have brazenly helped himself to my kids room. This makes me angry. It's like I'm giving too much space.
W told me get dinner on my own if I plan to GAL. I returned early to find out that W had made plans with him and our kids for dinner. He was there at my house does not surprised me at all. W asked if I would to join but I declined. I have gone to spend time at my parents.
The situation is like I'm ok with all this nonsense but I'm not. Need to push back. Or should I detach more?
Help!
