Long story short, my best friend is a cheater. She's married with 3 daughters and been with her husband over a decade. She says she loves him but she's always messaging other men and sending them videos of herself.
She trusts me and I'm the only person who knows but it's draining hearing her talk about it and how she doesn't feel guilty but at the same time she says she's happily married.
Her marriage is none of my business and I don't want to lose her as a friend, but the more she opens up the more I don't understand. She'll go to hotels with people and if her husband asks who she's messaging she will tell him it's me. It's like she does this all day and there's no guilt.
Has anyone had this before or how they would handle this?
