Up for debate.

I’ve always wondered why people wait until they have evidence or that person tells them, they are cheating on them. My father did the same thing with my mother and yes, they had been together for 20 + years but there was evidence of her sending certain photos to other people, messages and what not. But that wasn’t enough. The thing that actually made him leave was her friend telling him that my mother is cheating and she was taking her to do it, and as soon as he found out he has been nothing been feral towards her. Which I understand was in his right. But because of him waiting two years his mental state has never been the same.

Even he doesn’t know why he didn’t leave and before anyone says it’s a man thing. I’ve seen with my ex’s parents go through the same things this as well, when his father cheater on his mother.

So I’ve I’m wondering what does everything else think? Is this something normal in the world? I am young so he gentle. Please.
