While I get that you are hurtful because of what you feel it's your family "stabbing you in the back" I think you are also not taking responsibility for your actions and playing the victim card here.
For starters, you got in some SERIOUS problems and that caused your parents raised your daughter for about 5 years.
You married another guy that you are not longer with, which tells you aren't very good at picking partners.
Now you have another boyfriend and you expect your parents to be happy for you and ignore the fact that you have a list of bad decisions. "it's none of their business". Sorry but it is. You made it their business the moment you made them raise your daughter for years bc you were doing don't know what. So you expect them now to be sitting waiting for you to f*ck up again and hurt your kid in the process? Yeah sure.
"My mom and my brothers recently went to my ex husband and caused me to lose full custody of our son. " You have to be an unfit parent to lose full custody so don't come whinning now. Judges don't strip parents from custody just because, you did or didn't something that made a judge take that decision "this woman is no good for this kid".
Stop blaming your parents for your decisions. You are 30 not 15 nor 17.
"My mom also has been anonymously communicating with his family, telling them about something I did to them that may get me thrown in jail." If you did something illegal then you will end up with your sorry *** in jail for being a moron. Then, I said it. Normal people don't end up in jail for stupid reasons. Play stupid games, win stupid prizes.
"She’s telling people that she couldn’t come to me with her feelings, because I don’t listen and I’m confrontational."And? Are you telling me that's not true? Read above what you write and be honest with yourself for once.
"I have filed restraining orders on all of them and forbid them to see my kids. I never want to talk to them again. Am I right?" More power to you, but your parents won't live forever and when you needed it, they were there for you, taking care of your daughter despite not having to do it, FOR FIVE YEARS. You used them but at the moment they aren't dancing at the rhythm you want, you come with "buT tHeY aRe tErribLE" no. Stop right there.
Get yourself in therapy and stop playing victim. You are 30 y o.
