Yellow rose is absolutly correct. My H acted much like yours, and yes my H was great toward our children and grandchildren just very distant and cold toward me. What I kept in my head that they treat the ones they are closest to the worst as they are feeling loaded with guilt. My H actually told me he felt and still feels a lot of guilt and he is still working through his MLC .
Hold on to hope that you will have a new and better M and follow DB. It was my saving grace. My H could decide he wants out tomorrow and I know I would be ok because of DB and everyone here that helped me through H's MLC behaviour.
