The best revenge I’ve gotten on someone who had done me wrong was left them when they thought I wasn’t going to leave.
I used to seek revenge like doing petty things to humiliate the person or something like that, but I realized that in the end those types of things just end up making me look like the bad guy, no matter how many times they wronged me.
I was once friends and roommates with this girl who would create petty competition out of literally everything. It could be getting dressed, makeup, cooking, hobbies, anything! She had a knack of constantly setting me up to look stupid or inferior to her in front of other people, and even told other people she thought she was better than me. I respectfully confronted her on this behavior multiple times, but she would always either fake apologize or play dumb and go right back to setting me up to look stupid. After I realized she was doing it on purpose I gave her a 30 day notice that I was moving out, and did all the right things I needed to move (clean my room, notify the landlord etc) and she really didn’t believe I was going to move until about 3 days before my move out date.
Once it hit her that I was really moving on with my life she started crying and throwing a pity party for herself, basically begging me to change my mind and frantically trying to fix the things that made me upset. But it was honestly too late at that point because we both had to lay in the beds we made for ourselves (I wasn’t perfect either because I used to do petty things to get back at her) and I was already dead set on moving on. The best feeling in the world was when she visited me at my new place (uninvited) and saw how better off I was doing without her and left looking sad and heartbroken. That very moment I realized that I don’t have to get revenge on the people that have wronged me, moving on is truly the best form of revenge because it’s the last thing people want you to do when they’re backstabbing and betraying you.
