My ex broke into my house, so...
After we broke up, my ex-girlfriend and I stayed close friends. We lived together until our lease was up. I met the boyfriend who is now her fiancé. And she often visited my parents to help take care of our pets while I’m away. Because of this, my family and I decided to trust her with a house key. Even after the breakup, my family loved her, treated her like one of our own, and would do anything for her.
Big mistake. The day after I left home for a nine-month internship, my parents called to say that someone had broken in and stolen ~$800 cash. We checked the secret security cameras and, sure enough, it was the ex. My parents were devastated. For reasons, my parents decided not to press charges but just to cut ties, which we did a few weeks ago.
The revenge? I just found out from a mutual friend that her fiancé, who I thought was a wonderful guy, is cheating on her. Ordinarily I’d tell her; even an ex doesn’t deserve to be cheated on. But a backstabbing thief? Fuck it, she can find out the hard way.
Doing nothing can still be a form of revenge, right?
EDIT: For those mentioning the backlash that this might cause her fiancé, this just occurred to me: the guy is here via DACA from a fairly dangerous country, and I don’t know if she could use this against him in any way.
EDIT 2: Since a few people asked, I already confronted her about this. She denied it until I told her about the security photos. Then she immediately confirmed it, but vastly downplayed how much money she took. I told her to stay away from me and my family.
