At school drop off this morning a friend was telling me a story about her sister.
She found out her husband was cheating a month ago with a much younger colleague. She kept her mouth shut, gathered evidence ect...
She also saved up a weeks worth of his shitty, skid marked boxers and delivered them to the door of the younger colleague last Friday, smiling sweetly and saying "seeing as you love my husband so much, his ability to follow through after a fart is now your problem" and walked away.
I think reality hit as apparently the husband has seen the error of his ways over the weekend after the glam young woman in her 20s didn't think much of his shitty boxers.
Unfortunately for him, my friends sister had also packed up all his stuff and had it delivered to his work as she doesn't want him now either 
I wish I'd thought of that with ex h.
