The longest my xabf has ever been gone for was 7 days. His mother did file a missing persons report. When he did return, it was the same as always.......he would shower and go to bed- sometimes for days. He never talked about it really (unless confronted and even then it was me talking- him barely listening). He would try to hide out until things (people being angry, upset, etc) blew over. I feel for you though. It is a horrible feeling to be the one at home waiting. Even now, my ex and I aren't together, and I still worry when he takes off on a binge. Unfortunetly, I don't have any advice for you other than to keep on with your life and working on you. Find support for yourself.
