My wife and I coexisted for over two years with our children. I was hammered the entire time, with a promise list a mile long. Non of it ever came true. She finally got fed up and with the help of her friends dropped my ass, left and did not care. She even put a restraining order on me.
Guess what? Four years later I finally got sober - after MY trials and tribulations. She escaped the horror show it was for me to stop drinking and the hand cuffs, lot jobs, apartments, rehabs. She was out of the picture for my bottom and God bless her for it.
Today we are best friends. If you care about her, let her go. If you love her you have to leave or no one is going to survive.
