It's not a personal but someone close had been having an affair for years with a person, they had a wife too.
She decided to split, said she wasn't in love with husband and never had been but then told all family members that she'd met someone new and they were leaving their wife too. When it came to her moving out the ex husband paid for all their new housing, trying to help make her come back.
Month, she out of the blue denied all sorts of affair to family and went back on what she said, got back with husband (still lived in her new place) and went to councilling with him (whilst seeing this man in secret still). She eventually convinced him to leave his wife too (this ruined all relationships between him and his kids).
She rinsed ex completely.. She blamed him, blackmailed him, was pretty vile and it took him a long time to realise what she had done. She became abusive when he wanted to stop paying for the house they were both shacked up in.
To my point, she was so surprised that he came to that realisation what she was, that he pulled himself together, he told her to fuck off and he wasn't paying for her and her bf to live together. Been a few years but she's still genuinely surprised that he got over her leaving him and found someone else.
Sometimes people that arrogant think they're so invincible they'll never get caught, they're always needed and the person will always want them to be in their lives.
He underestimated you, he will never get to do that again. So much respect for what you've been through and done, he's a fool and he's done all this for nothing x
