Reddit, what's the cruelest thing you ever did to an ex? Did they deserve it?

I moved to Florida to live with a boyfriend. It was a terrible decision. He was 10 years older than I was, had no stable income, and lived with his mother. After moving into an apartment together (under my name only because he had no income) I realized the extent of his douchebaggery. He had failed to tell me that he was a convicted felon and that he had a child from a previous marriage that would be staying with us every weekend. Awesome.

After a month things go from bad to worse to oh my God my mother was right. He stays out all night working as a poker dealer, with his best friend Kristin. He leaves his daughter with me every weekend to babysit, he plays computer games constantly. I'm miserable. Sitting around all day in my pajamas playing Rift, smoking weed, drinking mountain dew mixed with rum and eating copious amounts of chicken nuggets, mashed potatoes, and pizza rolls. My life was shit. And I made terrible decisions.

Finally, I realize he's cheating on me with Kristin. Even then, out of sad desperation, I try to tell myself it's all going to be OK. I confront him. I tell him I know he's cheating. He denies it, so I show him text messages I had saved between the two of them. He snapped. He had the audacity to tell me I was crazy. I tell him I'm moving back home. His exact words, because I can never forget them, were "you are nothing but a little girl living in a grown up world. Go back home and live with your mommmyyy and dadddyyy. Because you can't handle your shit." I told him he was right and we'd finish out the lease for a few more months and just be roommates.

The next day when he was at work I started making plans. Went to the leasing office, bought out my lease. Called my mom and made arrangements. Packed up all my important shit and left. When he got back from working, the apartment managers had moved all his stuff out to the curb since someone was moving in the next day. He called in a panic and I told him that I had forgotten to tell him that I was moving out. Because you know, it's so hard to be responsible when you're just a child living in a grown up world. A lot of his expensive gaming equipment ended up rain damaged and he was homeless for months. Such satisfaction.
