In my case, it has focused me on healing. There has been virtually NO contact now since early Jan. I really have got to a point where I don't care either.
It's a sad situation, but I can also look back on it from a distance. I have no concerns over what W is doing, thinking or feeling about me or my future. I am in total control for the 1st time in many many years and it's truly liberating.
I used to worry about W, if she was missing me, if she was OK, where she was and what she was doing. Now I know that my 2 boys will let me know if there is a serious problem. If not, then I don't WANT to know anything about her life. She chose to leave, so she can do without my concern.
Last time I talked to MIL, she asked me how I was and I said great!. She was quite surprised.
