I'm so sorry that your are here, Klassic, and for the situation you are in.
Your efforts to help yourself are very admirable. I agree with PigPen. You XH needs to heal, as I suspect you do, as well. Perhaps continuing to have physical relations with your XH is very confusing to both of you right now? Certainly pursuing him is unlikely to be a helpful strategy.
