OK, here is a update. I think this is a lost cause and wife is over the edge mentally.

My wife is under unbearable stress and just wants to run away as fast as possible. Its difficult for me to understand b/c hasn't blamed me much, and I have not been difficult (never touched or even raised my voice at her), but me talking about fixing things is a big problem for her so I stopped doing this. There was a note left on the counter (acidently by her), when I was cleaning up last night I saw it. Its probably something the kids found and put there? She had a list of "untrue" things that I did:

I called her boss and told her that my wife was mentally ill - (I have never called her boss)

Bugged her cell phone (I don't even think this is possible)

Continuously calling her family members to tell them she is ill (I texted her sister once to tell her I was concerned for her and wanted advise on how to help, she never called me back)

I have a tracking device on her vehicle (Not true... but I think this is based on me taking a half day one day last week and she was home asleep when I went home... and she thinks I went home because I knew she was home).

I've heard from others that she is telling them I am threatening to take the kids from her. We haven't even discussed custody much. I've said anything other than I am concerned about how custody will work out.

I don't think I have a option now other than to be supportive when I can, always nice and calm, and try to protect my kids and myself legally.
