Is it best i leave him when he needs me?

Well idk if he needs me or not, and just saying that he does. But i cant take it anymore. My husband also told me that hes really tired of me, along with being tired w everyone and everything. Our neighbor threatened him and theyve been having problems w each other. Police doesnt do anything about it, which is making him super stressed, and lost hope in the justice system. He said he feels like theyre taking the dudes side and he feels like hes the suspect. Theyre not taking this seriously, the neighbors a criminal, and has had criminal history. Anyways, my husband told me that im so useless. Im no help to him, he has to do everything, mind you, i called the cops for him, and i also emailed them evidence. All he had to do was speak w the cop and file for restraints. While i do the research of how to file for one. He says hes so tired of me, all i do is sit my ass. We have 2 babies btw and im the only one doing everything in the house. I told him we need diapers so we have to go shopping, nd he was all mad, saying that hes so fucking tired of this shit. Having to go buy baby needs. He said i make his life worst, im a burden, im useless, stupid, and a bitch. Wtf i wven do wrong to him. Im thinking i should just leave him cause he obviously dont need me.
