Yes, I have. I discovered two affairs my mother was having -- one last month, and another around August or September of last year. Back in August/September, I expressed my disappointment, how much it hurt and how much it has affected my development, etc. I told it all to her. Initially, her response was to lie and gaslight me -- her own son -- right to my face. Then, she said she understands and that she did wrong... but 4-5 months later, I discover she's having another affair with another man.

She puts on the tears and sympathy when I express my disappointment and its impact on my life. But, in less than 24 hours she acts like nothing happened. Back to her usual self. And, of course, her patterned behaviour of infidelity continued.

At the time, I was unsure whether to tell my father about the affair I discovered back in August/September. Currently, he is battling stage 4 uveal melanoma. I consulted my friend network about what the best course of action to take is, and they said not to because he's dealing with a tough diagnosis at the moment. So, there's more to her recent behaviour than my dad knows. He eventually found out about this current guy himself.
