I just feel so worthless 😔

I just feel so worthless, how do I move on. Me and my bf been together for 4 years, and we have a two year old. He literally does nothing for her, I have to ask him to buy her stuff and the last time he has done something for he was a year ago.. my mom has to take me to all her appointments, get diapers etc. He is abusive, he kicked in my room door, won’t give back the key to my house and when I put something on the door he kicks in the air conditioner. We had a domestic abuse case but he beat it, he told me if I didn’t show up they would throw it out and we would be a happy family, and he would help out with our daughter and let me relax since I’ve been doing everything.. so I didn’t go and it was thrown out.The case was closed two months ago and he still has done nothing, I just feel so dumb for believing the lies and thinking that he would change and we would be a happy family and looking past the abuse he’s done. I try so hard to be done, I’ll block him and when I see that he’s called so many times I unblock and the cycle just repeats.. I truly want to be done and just move on I’ve wasted ages 17-21 with him thinking a fairytale in my head would come true because of the lies he fed me.
