Search Results: My ex boyfriend is talking crap about me What

So my ex boyfriend who was abusive and cheated on me with my sister is who this post is about. About a year in our relationship he began wetting the bed and I was very supportive. Even though he put his hands on me and treated me like crap. As a last ditch effort I went to his mom about it who then told me that he did this in school and she had a bunch of tests ran with no issues at all causing this. Finally he admitted to her that he wanted to wear diapers again and had been wetting on purpose. She didn't let him and through the years found wet diapers he had gotten hidden in his room. After talking to her I wasn't going to even bring it up. Hoping if that was the case he would tell me. Then I caught him with my sister. He begged me not to leave and so a light went off. I told him I would stay if he told me why he had wet the bed and that he better not lie bc I spoke with his mom. So in tears he told me he wanted to wear diapers and be treated like a baby. I agreed, but on my terms. I was in charge and if he wanted to be treated this way it would be a constant thing. Even in front of friends, family, and strangers. He was worried, but agreed. So I began taking action. With his mom's help our spare bedroom became his nursery. With a crib. High chair and changing table. I began taking him in public in his diapers, onesie, and pacifier. He had to use his diapers. The toilet was off limits. My friends often came over, teasing him. We aren't together anymore. I moved on. He now lives at his mom's again and is still in diapers 24/7. I go from time to time to talk to her and check on him for a laugh.
Seeing how abusive he was, cheated on me, and lives like this with all his relatives and people in town knowing what should I do?
