How are things going ? Truth is you know the right thing to do and its only fear that is holding you back. Reality is she is getting needs met by OM at present , as hard as that is to swallow. There is little that you can do that will have any visable effect. However you can bet that she notices the changes , but will not admit it. Your challenge is to rebuild your life without her . You will still miss her and it does not mean you are giving up. The very act of looking after yourself and making your own life as good as it can be will make you a more attractive person. Standing up for yourself ( that will mean standing up to her ) may earn you a bit of respect from her as well.
