I would blow up my BFs car if he had one or his house.
If I knew the girl (friend, cousin) I would do the same her shave off her hair
If I didn't then I wouldn't do anything

If it was a one time thing, I'd shrug and ask if /hope she had used protection. Then pardon it.
Maybe I'd have an ONS with someone else, just to try.
If it was recurrent I'd shrug , split like civilized people and walk away.
No drama, no revenge in either case.
