Now i feel terrible

My husband and i are not doing well. We cant go a few days without arguing about something stupid. Im so exhausted. We have 2 toddlers and when he is upset he will not help with morning or bedtime routine. I work from home and my mom and sisters live next door to us, so i take the kids there. My family knows the situation because i always vent to them. My husband is also short tempered, he will go off over anything so our problems don’t get resolved and the only way for me to move forward is getting it out somewhere which is usually talking to my mom or sister. Well today husband went off about something he couldn’t find. He didn’t like how i responded, the whole thing went south, you would think he found msgs to another man or maybe i stole money, something very serious but no it was ridiculous. He wouldn’t let me leave, all in my face, both of us yelling and screaming. I finally leave our place and he follows me to my mom saying he wants to talk to her to tell her how disrespectful i am. My mom opens and we sit and starting talking but emotions are high, the conversation goes no where. My sis who was watching the kids comes and starts yelling at my husband saying he is a bad father and husband and needs to leave. It got so bad.!!i feel like its my fault for telling them everything. The way it was handled was just out of line but i also understand they are so tired of me hurting. My husband finally left after screaming that he is divorcing me and will bring papers for me to sign. Honestly im not too shook about that but i feel like my family especially my sister didn’t have to get involved in that moment. Maybe i am nervous about getting divorced, but we fight so much and he refuses therapy and has anger issues, but its good he finally leaves me because im probably too weak to walk away because i always want to believe things will get better.
