AITA for “shitting on ” my ex and her new husband?

This is a weird story and I am not trying to brag or anything but I feel like an asshole and it’s been bothering me.<br><br>I used to race mountain bikes professionally. I was pretty good. Like top 5 in the world at one point. Of course, I was young and completely arrogant and entitled. Even though I wasn’t that old, my body was deteriorating. I had broken almost every bone in my body at least 3 times over, including my collarbone (like 15 times), both my wrists and arms, legs, ankles, I even broke my neck (not that bad though, only 2 vertebrae had to be replaced with artificial ones). <br><br>Anyways, I had a girlfriend for about 5 years. We started dating when I was at my “best” and we broke up almost right after I quit due to my injuries. She was always really nice to me but I found out she was cheating on me for the last 2 years of our relationship with her now husband. It was a really dumb thing to do but instead of just breaking up with her, I decided to “get my revenge” on her for cheating on me. I “dated” her for a few more months and basically only had sex with her. She was a power addict and was completely submissive sexually. I basically blackmailed her into doing whatever I wanted and she did not say no to anything. She was very into whatever we did and would ask for it repeatedly but it was manipulative on my part and I know that now. Anyways that’s in the past.<br><br>Basically 3 years later I get a message from her asking if I could meet up. I said we could meet at a coffee shop and she did. She said she got married last year and that she got pregnant right after. She had really bad nausea and the doctors couldn’t find out why. She had a miscarriage and said she felt like she could finally focus on her relationship with her husband. She said they are thinking about having kids together and she needed to get something off her chest. She asked if I would be willing to do a DNA test with her and her husband. I said sure. Why not, it’s not weird for me. I didn’t mind. <br><br>We did the DNA test. Then, two weeks later she contacts me again and says she’s distraught. Apparently, the DNA test said that her child was mine. I was surprised. It had been years. She said she was upset because she had no idea I was the father of her child and that she felt like she needed me around because her child was mine. I don’t know if this is just to manipulate me or if she’s actually telling the truth. I know I’m not the father, the dates don’t match and I haven’t seen her since we broke up years ago. <br><br>She said she needed to get closure of some sort and asked if I could meet her and her husband for dinner and talk it out. I said yes and we met at a fancy restaurant. She and her husband were dressed really nice and they were super rude to the waiter. I couldn’t stand people like that. Anyways. We sat down and they had a whole speech played out about how they were going to tell me that they know I’m not the father of her child but that they wanted to tell me that she thinks about me all the time and that she was going to leave her husband for me if I wanted her back. She said she was actually in love with me and didn’t know it. <br><br>I was completely disgusted. This lady was married and she was trying to say she was going to leave her husband for me? As if I have any say in the matter. I told her I wasn’t interested. Then I told them that I was conducted an experiment of sorts at the dinner and that I had shit in my pants right before I sat down. I said that I wanted to see how long they would let someone sit next to them who shit themselves before they said something. I got up and walked out and they started screaming at me.<br><br>They have been harassing me ever since. Sending me texts and email, saying I’m a disgusting person. Her husband contacted my work and said some not so great things about me that got me in a little bit of trouble.<br><br>AITA for shitting on them?
