Is it okay that I made a fake tinder profile and made my ex feel like an awful person.
Why did you want to make your ex feel like an awful person?
It was fun and they lied to me, treated me so badly so I thought "fuck you, you deserve it"
I get it you were not happy with the relationship. He's now your ex so you should move on with your life instead of getting back at him.
I agree but I'm going to fuck with him a bit more till I feel better.
The relationship is over, let it go already. You're only wasting time and trying to satisfy your own taste for revenge. Forget about them and use your time to find someone else to start a romance with.
