That is so hurtful. Please try to protect your vulnerable son Betterdays. He has been through so much all of his life at the hands of his dad, this blocking him will hurt him even more. At least you are the One Good Parent that was mentioned before on here, your son will know that too. Maybe you could say to your son that his dad has had to take some time out at the moment so will not be in touch for a while?, I don’t have children so i’m not sure of the etiquette in these sort of things. Thinking of you and your sons at this difficult time. X*X
Your ex cannot cope with all what is going on, so they do what they think is best to cope, putting their heads in the sand and putting it out of their minds. Don’t forget karma, what goes around comes around. He will get little reminders here and there throughout the day of his wrongdoing, it will gnaw away at his conscience. He might not admit that but might resort to increasing the alcohol or fighting to cope with it. In the meantime, you take ultra special care of yourself and your sons.
