After 15 years of unhappy marriage, I finally grew a pair and divorced him. Found out he was cheating towards the end anyways. We have two kids at home, one mine and one ours. They are teens. He was with the cheater girl for a few months, (divorced 6 months ago) and now he is with another girl(long distance) one month with a 10 year old. She is oblivious to his history of drugs, abuse, lies, cheating, absent parenting and even worse spouse. I tried to warn her, but he has got his claws in her and is being told that I am just the crazy ex and not to listen. He still messages me that he wants me back and I have screen shotted them and showed her, but she will not listen(love is blind), they did not spend the holidays together and he did not even call his kid for Christmas. How to I make her see his ways and avoid my son having to endure the latest tartlet that he is with. He only has him on weekends to impress his girlfriend, he is a terrible father and Karma is not working fast enough.
