Dealing with a Conspiracist Mom and Enabling Family Members

I'm not sure if anyone can help- but I just want to feel comforted. But, my mom is extremely into politics/conspiracies and wants to always force it onto everyone and always denies that she does. I'm 21 and live with my husband in my families house with both my 10+ yrs old older brothers that I cant really get into as to why im back living with my family but its basically cause I had no where else to go so ive been here since Feb 2020. This is my eldest half brother's house who is 37, and my mom is enabling him since he went into jail for being an alcoholic and domestic abuse towards his ex wife and my 2 nieces. So my mom has enabled ever since then and thought it would be a GREAT idea to have everyone live with him so he gets back on track from Marijuana and Drinking and that it's a bigger house so she too will be happier-- Boy was she W R O N G and doesn't even realize it. I have recently found out that I am a people pleaser and need to have more boundaries. So I started to do so, so just 2 days ago I woke up after having recurring dreams of speaking up for myself towards everyone so I went to have lunch and mom asks " how're you doing? " I told her I am no okay- I am Irritated. She then forced a hug onto me and asked if I wanted to go eat with her & my dad. I firmly said "No" So basically let me just say (I would go into detail but my messsage is too long already) that I got really upset and angry and told her she doesn't even know the real me and I will NEVER believe what she believes in. She then proceeded to hope I feel guilty for what I've done and slammed the front door while she left with my dad. mind you- she has done this my whole life. My Husband is currently working so we can hopefully get out of this place so I can cut ties. I'm just curious if anyone else is going though anything similar or has any advice? This is really hard on my mentality so anything is appreciated.
