It is not hopeless, but you must not discuss the marriage relationship (MR) with your W.....no matter how much you want to. Don't push for MC b/c right now she is not willing and it will not go well. Give her time to cool down and give her lots of space from you. No more contacting her unless it's an emergency.
Don't worry about her not seeing your 180's due to her not being with you. That gives you time to perfect your changes. She will hear through others about your changes. Remember, make the changes for you! Become the man any woman would be a fool to leave!
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
