First, Sorry you are in your sitch, but you found a great place for support.
This is a great opportunity for personal growth (if you choose to take it).
I assume you want M to work. You have all the power to change the R (without needing to "TALK" about it with H. You have full control of your thoughts, words and actions. Change your thoughts, words and actions and you change your relationship. It is that simple. Become the woman you have always dreamed of. Surprise H during every encounter. Behave unexpected. Project happiness, confidence and sex appeal.
Love is a choice. Love = Patience and kindness. Forgiveness is a gift you give yourself. Forgive others and yourself for past hurts. Focus on NOW. Do not fear the future.
DO NOT CHASE H. Draw him back by changes in your behavior. Be very cognoscente of his reactions to you. Stop doing anything that pushes him farther down the D path. Continue doing things that show him what he will be missing if he leaves you....Be more attractive than his "Fantasy women".....
