I'm sorry you've reached this stage. The ease with which our WAS's can cast us aside does not cease to amaze me.
You said you are tired of feeling this way; I hear that. We want to feel better NOW. I don't have the magic formula or answer, but I do know from my own situation that the knot in my stomach is very slowly getting smaller; thoughts of my W are not constantly there; my house is not quite so depressing and I am not sad all of the time.
Your W took the easy way out instead of doing the hard work a marriage requires. She's already throwing herself into another relationship which will probably have similar disastrous results. Does that help your situation? Of course not. But you are on the road to self-improvement, a better outlook on life and eventually you will be a better partner for someone. You will know what not to do as much as what to do.
Right now it is painful and hard to believe it is happening. But it is not the way it will be forever...a trite cliche, perhaps, but it is the truth. Allow yourself to grieve, then start to GANL - Get A New Life.
