Should I move into my grandparents with my mom?

So my mom lost her job back like 4-5 months ago and we’ve been living on savings. In our area that’s not lasting long. She got a remote CDC job. But it doesn’t pay enough to stay where we are and she has student loans. Now my grandparents live in Las Vegas in a really and mean really nice neighborhood. Thing is my family is pretty messed up. And my mom and grandma happen to be getting along right now. They will not get along soon. Thing is my dad who is in my life has had his job for the past 10 years hasn’t moved and could provide a steady life where we won’t move around all the time. My mom just got out of an abusive relationship with her ex fiancé when she got her job after she spent the last 4 years getting her degree. My brother (11) and I (16m) were living with her and her abusive fiancé those years for the school weeks. I don’t know how to feel. I want to live my dad now but I think it’d be selfish of me to not move in with my mom and grandparents even though they have had a horrid relationship in the past and I generally feel miserable in Vegas. My dad lives in the country and I love it here. I hate Vegas.

TLDR: is it wrong of me to want to live with my dad who has a steady home and job than to move again and again with my mom and go through more rough times with her?
