Basic facts : I'm 20, 2nd year of good private school (partial scholarships so not crazy expensive), dorm at school, STEM major, good gpa, lift, decent physique, overall on the up and up implementing trp into my daily life.

Now for the negatives and my current situation, my mother is a decent lady, some legitimate mental health issues, very emotional and overprotective but cares for me and others. Her husband of 4 years (step dad) is on surface a decent guy, has stable job, kinda wimpy, no hobbies,watches TV alot, your typical middle aged beta. Underneath the surface he is extremely particular and anal with every detail in life and is an absolute prick to everyone that isn't a female family member (including my mom). Even with them he is an asshole but eventually they yell at him or throw tantrums and his frame crumbles and he comes (literally) crying back to them.

My dad is a textbook natural alpha and helps me out how he can but he has a foreign wife that is very crazy and causing alot of problems for him so how he can help me is limited.

My mom has a low paying job and is not financially well off. When her and my step dad married she wanted her independence meaning they split the bills and she has equal say in all major decisions.

Fast forward to my recent issues, his landlord wants his son to move in so he's making my family find another place. My mom has had some semi serious health issues recently (not dying in the next 10 years at least but not a joke either) and he's been supplicating and taking total care of her like the good beta he is, of which I am thankful for, despite him not actually leading their "ship" anywhere meaningful or having a solid frame and plan of action. Anyway, step dad wants to move over an hour away from our current location in the middle of nowhere and I am without a car. He's become more and more of an asshole to me over the years and since my mom's health issues it's gotten worse and it's like he takes whatever frustrations she causes him out on me whenever I'm around and always assumes I have the worst motives for everything.

I've tried to bite my tongue for a long time for my mother's sake but it's gotten worse and I just can't respect myself if I remain in this environment so I am thinking of getting a room and job for my school breaks and living there. I have a few hundred dollars saved up that I didn't tell my mom about in anticipation of an event like this so I'll be able to afford my first month while I get myself set up with a job or two to afford the (not expensive) rent.

Normally I would just nuclear the situation and make my mom side with me over him but the truth is that she really is better off with a stable man around than being alone and I'm not around for most of the year when I'm at school and I'm not sure if I'll remain in the area once I finish college so I've bitten my tongue so she remains taken care of.

My friends are (obviously) telling me it's a good idea and I should do it but I wanted to get the opinions of some more experienced individuals from a unbiased perspective to let me know if I'm acting on my emotions or being too rash, since once I take the step I don't think there will be any turning back. I'm confident in my abilities to take care of myself but I just want to make sure I'm making the right and smart decision.

Thanks for your input.
