My mom says she’s leaving her abusive husband but my dad doesn’t want to help her

My mom calls me this morning and tells me that she’s finally tired of the way her husband emotionally and verbally abuses her, and she wants to leave. She’s told my sister this on many occasions but she always ended up staying. I have a 9 year old little brother who lives alone with them. I don’t know why he told me this morning but she said she’s tired of him slowly killing her by bringing her down all the time. She told me not to tell anyone that she plans to leave. She asked me if she can keep a few things at my house (an $80 fire pit and some heirlooms) so she can try to figure out the next steps. She says she’s meeting with an attorney on Thursday to see what her options are. I told her yes because more than anything I want my little brother out of the situation. It has affected him mentally.

I don’t have a great relationship with my mom. Mostly because of my step father. He abused me and my sister and brother. We all managed to get out. I have not spoken to him in years, even though we go to all the same family functions. She is definitely to blame too because she basically chose a man over her own children. My dad and I have a great relationship on the other hand. We talk everyday and he has been there for me emotionally and financially. He truly is a good person. I live in my dad’s house, and my dad is a caregiver and moved in with his patient.

I called and told my dad about what is going on and at first he said it was fine that she bring those things over and we can keep it in the guest house (basically just a storage place). But then he called me back and told me that he isn’t comfortable with it, my mom has spoken badly of him in the past, my stepdad is psychotic and there’s no telling what he would do if he found out she stored stuff at my house.

I feel so incredibly conflicted. I understand completely where my dad is coming from but at the same time I want her out of that situation. Mostly for the sake of my little brother. It hurts my heart knowing that he’s stuck there all alone with two toxic parents, and if there’s something I can do, even if it’s small, I want to do it. I think my mom would be a much better person if she left him and maybe we could work on our relationship. My stepdad has caused so much damage to everyone. My boyfriend offered to keep her stuff and I just don’t have to tell my dad so that is an option. But I’d feel bad involving him.
