I don’t know the particulars of your situation but I am here to tell you that with time the pain will go and you will be nothing but happy that you made this move.
4 years ago I learned that the man I had loved and trust for 2o years had had secret girlfriend for over a decade. I showed him the door and haven’t seen him since. I was totally devastated. Four years Later I am happy again and I love my life. You will be happy again too
Fuck that guy.
