wildgarden,
Though not married, I have just broken up with my A and I can tell you it is one of the most painful things I have ever had to do. All the broken promises and mental abuse are too much for me to take anymore. I am glad that I am out of the situation and will not be seeing him anytime soon.
May you find peace in the future, it may be a tough time for a while, but once we get through the tough parts we will be better off.
