I messed up...help

Guys I need advice I messed up, so there's this guy that I've been messing around with and I have really strong feelings for him the way he feels about me is complicated and that's okay that's not the focus but he kind of like really did some dirty stuff and I was feeling very heartbroken very sad so to get back at him I felt like since he was a dirtbag I use the dirt by mail service and had them anonymously send him a bag of dirt with a card that says you're a dirtbag. Now he and I are close again and I feel bad about the dirt bag he's going to get on Monday. It is anonymous so it will not say who told them to send it but I still feel bad and there is no way to stop him from getting it.
