Name change for this one
My SIL and I are very close, best friends. My DB is a pain but I love him. They have 4 children. She confided in me at the weekend that she had her second affair last year, this time with our mutual best friends DP. They have 3 children.
The reason she told me is someone else knows and is using it against her so she wants me to back her up if/when it comes out.
DB suspected last year and we all told him he was mad. She would never do that again as she nearly lost it all last time. I sat and listened to her for hours about how DB was making her life miserable with these accusations, he was right with the timing and the person.
The man in question is a sleaze, always has been and I long suspected he had cheated on best friend many a time. If it comes out, which it will do, that I knew (after the fact) I run the risk of losing DB and best friend. If I tell I lose my SIL who is also my best friend and blow up 2 very interconnected families and a wider friendship group.
It’s over and has been for a while, he’s moved onto SIL other friend who is not really in the group. Despite the fact best friend thinks they are trying for another child.
I want to tell. I’m dammed if I do and I’m dammed if I don’t. I wish she hadn’t told me!
