I started here very enthusiastic about saving the M (by changing myself). but i am gradually losing my enthusiasm for saving the M
Here is my take on it.
Your marriage was over at bomb drop. Everyone who posts here is in the same boat.
Can you build a new marriage? - Yes Whats it going to look like? - hopefully better that the first time around
There is no going back only forward, the things that MR Bond is hammering you on you need to change whether it is to save this marriage or if you have another marriage to someone else.
If not you will just be right back here again with the same issues - rinse - repeat.
