Am I crazy ?

My daughter’s dad has been emotionally and sometimes physically abusive to me. He’s calling me a bad mom because I work 5 12hr shifts a week while he sits on his ass and plays video games and complain about not being able to buy weed. I broke up with him back in November he argued with me every single day he would get mad if I didn’t say that we were together and it got to a point where one time I got out of the car mid argument and walked home. I’ve put him out at least 6 times I only let him come back because we don’t have the family support and if he isn’t able to watch her so that I can work I don’t have any one else to rely on to help . She’s in day care but I work in the er and my shifts don’t end til 7 & my supervisor isn’t trying to work with me about leaving early . So I’m stuck in a hard place. He’s constantly picking with me he threatened to file for full custody ( which is funny considering he doesn’t do anything for us he watches her and feeds her junk food all day and when I come home she has a diaper on her that’s so big it’s basically falling off of her) we argue about him not trying to find a job or do anything I’ve called his friends and family for some type of help because I can’t put up with this anymore they just keep saying “we know he loves you and you should just unplug the Wi-Fi and maybe that’ll set him straight.” 🥴 I’ve asked them to come get him( his car got repossessed a few weeks ago because he wasnt paying his car note for 6 months , they felt that I should have been helping him) I’ve put up with this for almost 3 years not to mention the day that I had a complete mental breakdown and tried taking my own life he beat me up and called his family crying and their response was “ you need to leave her she’s obviously not capable to be in a relationship or be a mom” let’s not mention the amount of times he put his hands on me while I was pregnant and the day after I got discharged from the hospital with my daughter he put his hands on me and got mad because I wouldn’t have sex with him. I’ve called the police on him so many times and the judge told him if I don’t want him around he has to leave or he’s going back to jail for years. He doesn’t care about that , if I had a stronger support system I would have been left but I just don’t know what else to do . I had a plan today to wait til he fell asleep to handcuff him and beat his ass with a belt then call the police and have them take him away. Im tired of being triggered by him and he’s saying things to get under my skin but when I react I need to learn how to control my self and “change”
