need advice

to make this short ill get straight to the point, my dad used to touch me and a co worker few years after attempted to abuse me told my mom and to both situations didn’t believe me. She said i started it somehow. this went on for years constant fighting im 20 btw. all i wanted was to get along with both my parents and move on. but recently beginning of April we were fine and out of no where mom said im only fucking up their life and to figure out mine however i can, so i told her that i’ll leave the house. She saw me pack and didn’t say a thing the next morning i was out of there. left with my boyfriend at his parents house and i have my own room there. They call me now saying i decided to leave on my own and why would i go to my boyfriends without being married. should i move back in?
