Anna, I wouldn't wait to see an attorney. If you wait, you will be left to reacting to anything H does. In order to protect yourself and the children - as you know he is not completely rational right now - you need to be ahead and not run behind. Seeing an attorney is not a commitment, it is just a way to find out what your potential avenues are, going forward. I am worried that you may regret not having informed yourself of your rights and options.
My H kept saying he wanted to be fair, that he was looking out for me, while he hired an attorney behind my back and tried to block my entry to our marital home. He also thought that I should just go live with my son without any financial support from him, in another state, and start rebuild my life from scratch. I stayed home for many years taking care of his children and his mother, so I don't have a retirement or any experience from the job market in recent years. When I talked to an attorney, I got information that was very, very different from what H thought was "fair". It was very empowering, and made me feel a lot better about my situation. It took away a lot of fear and uncertainty I had felt. I also believe that it made H reconsider his decisions and snapped him out of the fog.
