Someone did something really horrific to me years ago - told his wife that I'd tried to sleep with him when I didn't. It led to an awful shitshow with a huge fallout amongst friends and could have had serious consequences as he contacted my DH almost every day as it all played out over a couple of months and tried to persuade him he was telling the truth (DH didn't believe him) and in general I've moved on and don't think about it all that much.
However, a petty and vengeful part of myself really wants some form of payback - it irks me that he could just do that, get away with it and (for a short time) upend my life. I don't suppose there's anything I can do at this stage is there? Has anything like this happened anyone and have you managed any form of payback to the perpetrator? I mean this in a lighthearted way, although it still annoys me that he could disrupt my life like this just by lying.
