Dealing with my father who is lying to and about me
My father and I shared a close relationship for 48 years until my mother died. I'm an only child. I had a difficult relationship with my mother due to her aggressive personality and insistence that she was always right. She died 22.214.171.124 years ago and while she was dying and immediately afterwards - unbeknownst to me he established a relationship with a woman who became my mother's best friend while she was dying from pancreatic cancer. He didn't tell me about this new relationship until they had already become committed to each other. My father always had narcissistic tendencies, and his new woman (whom he married a year to the day after my mother's funeral) indulges him in these tendencies to the point where he became insufferable. I haven't seen him in seven years or spoken to him in six. It is on my heart to do something about this, but because I intrinsically knew he was lying in the beginning I couldn't accept this new relationship. Since then I have found out that he has repeatedly lied and defamed my and my wife's character to many people, while trying to contact me maintaining that he doesn't know what he's done wrong.
Is there any point to trying to re-establish contact with my father at this point?
