It will go on longer than you want it to, but it will be over sooner than you think. For what it is worth, my wife is as hard headed as any person I know, stuborn to the core. She was done, completely, and I fought threw it, just baby steps is all I was after.
Still going through them as well, for example. Goal #1 have her say she is willing to try to work on our m. #2 have her see mc #3 have sex with me #4 have her touch me lovingly again #5 have her say I love you to me unprovoked (this one happened only about 3 weeks ago.
I recommend doing these little things. As you can see it is a long road, but when you list out your goals, and not the ones I listed, maybe real small ones, like she calls you by next Monday, or something like that, you feel like you are making headway. All the while as our stubborn women think what we are doing is all show, we keep hammering away at them by showing them that we have truly changed. Even the most prideful will start to question themselves.
