Venting: my mom likes married men

So my mom split up with her abusive boyfriend in 2015. He caught her exchanging messages and phone calls with a man who lived in another state.(Like lovey dovey calls) he went psycho and said he was gona kill her, he urinated on all her clothes and cut her face out of family pictures. Anyways for the longest time she played the victim card and got away with getting favors from everyone and help. Unfortunately it’s been 3 years since her split and she still acts like a victim and gets people to do what she wants that way. Anyways, after her split she started talking to MARRIED men. Which for a while I believed what she said, “he’s just my friend, his wife wants to add you on fb because she’s a crazy jealous witch and wants to talk crap about me” so I never added those women. We had a falling out on 2016 because she was doing a lot of things she wasn’t supposed to be doing, like sneaking out at night leaving my 6 year old sister under our “SURPRISE” supervision (where she didn’t tell us anything, we’d wake up to my sister crying because she was alone). Then one day she moved out by surprise, and left us in debt of the apartment we had mutually agreed to rent. A couple of days later, an older woman, comes up to me to talk shit about my mom, and how she had proof that my mom sent nude pictures to her husband. And that they were talking. My mom is now with that man and has been for about a year, they had been married 22 years. NOW, another women who is my aunts sister in law. (She’s my aunts husbands sister) she messaged me on Facebook saying the same exact thing. That my mom was a whore and that she was messaging her husband and that she had sent nude pictures thing a marriage of 30 years. So all the times my mom called a woman a jealous witch kinda clicked, and in total she’s done this 5times or more. I’m shocked since she always beat into my head “a married man is a castrated man”. Oh and the man she was talking to when she split up was a married man. She also betrayed her best friend by dirty talking to her husband and accepting gifts and ruining that marriage too. Like is there a mental disorder for this ?? I keep trying to find an explanation but I can’t other than she’s a horrible human being. We haven spoken since 2016 since she ruined my reputation and credibility Making rumors about me so that I wouldn’t out her on her secret. (Since everyone sees her like an angel)
