Just empty the bank account and emigrate!
Having had enough of negotiating with an ostrich in denial, I simply emptied the bank account, disappeared one weekend he was away, and emigrated to Australia. This must be the shortest version of that story ever told, but it is true! Definitely can recommend starting over at 40. Best thing I ever did.
PS - I am a strong believer in forgiveness - it can make you feel almost as good as revenge LOL.
