Split with what to do

So my dad recently had bought a house and he is letting me and my sister move in there yes we will have to pay rent and other bills I would really like to move in there because my dad flipped it all by himself but I’m split in a decision because me and my boyfriend just got back together we broke up mainly because my parents didn’t like him at all and they were controlling about when I could see him(I’m 23) and he has his own place now and he is struggling paying bills he asked me to move in with him as soon as I can so he can have help and so he will be able to see me whenever he can, but I have no clue what to do and I don’t want to tell my parents that I am back with him because I know they won’t talk to me for years. So the question is if I do move in with my boyfriend what should I tell my parents and if I stay where my dad bought a house what should I tell my boyfriend?
