I wanted to add that I really have been trying to follow the advice here on not pursuing or pleading or begging her to change her mind.
I do want to save the marriage.
I limit contact to only necessary emails about the kids and finances. I don't include her in any family activities. I don't stay in the same room as her.
Sometimes she'll make conversation and I'll listen and reply in few words. I've limited my presence around her. I don't sense as much hostility from her as I did during the first few weeks.
I'm also GAL and doing 180s.
It takes a toll on me and I'm tired all the time. I sleep in my car during lunch breaks.
I want to go to the gym and get my energy back.
I need to work on validating and detaching as I haven't really started this yet.
