Hi everyone. Thanks so much for your replies and support last month. Things got much much worse as ex had nowhere to go. But finally, after weeks of him drinking heavily, feeling sorry for himself and swearing that every day would be different, he has finally moved out. I feel the most amazing sense of freedom and I understand now how much this impacted on me. I wonder if there are other people who can cope with it....but I am not one of them.
I am looking forward to the future. I hope he gets better, for his sake and that of his family, but I am out.
