something in the way you are currently dealing with you W has caused her to "feel" differently about you.
I know that you are in a DONT GIVE A F frame of mind right now.
Since you have 6 years to go, why not experiment with some other ideas on what women will respond to.
You have allready done the most difficult part of losing your anger and dropping the rope completely.
I dont know how long you have been lurking, but to you I recommend getting a DB coach. There is a famously succesful and well respected man on this board who was plotting and planning the same thing you are. He figured WTF might as well do something while I am waiting.
If your anger and Resentment are so deep that you want to do this to 'pay her back ' for all the previous years, even if things were to improve, well honestly I understand. Dont agree, but I understand.
and lastly ditto GEL. If you dont have constructive criticism, or uplifting comments venting or even commisserating.
Shut your pie hole. Go plot your D somewhere else.
