Personally I would not have left the house. Nor the bed. But with you going away to school again out of state perhaps now is not the time to go back. That I will have to think about. But I would document why you left and what you thought it would do to save the marriage. I would also document all the times you got to be with your children and if you were stopped from seeing them. Document your sessions with IC.
The school is here in town where we live, which is one of the reasons I picked this particular program. It means that I will be able to be able to further my education and still be close to my kids and my W. I have been told that I made a mistake by leaving the home but I don't think I did. My goal was to use it as an opportunity to detach. The problem is that I did not do a good job at it. And to be honest, at the time I left the home she did not tell me that she was filing for divorce, she just said that she thought we should separate for awhile.
