How do I tell my mom im moving into my boyfriends parents house?

ok so, me and my boyfriend have been dating for about a year and about 4 months. me and my mom have been constantly fighting all the time and im just sick of all the drama. my mom and my boyfriend dont seem to get along very well, and my boyfriend never comes to my house anymore because of a thing that had happened earlier this year. me and my boyfriend have last period class together ( were in highschool ) and my teacher called my mom saying that me an my boyfriend do inappropeiate things in class. the only thing we do, it a little odd kiss, when shes not teaching, and we scratch eachothers backs, and heads. we do none of this during her lessons. but anyways she over reacted about the whole thing, and called my mom. she says that I should control my boyfriends actions and tell him when you wanna say no and that I dont stick up for myself and I dont really care about anything. to be quite honest I dont really care what people think. I dont really care I am who I am. and my boyfriend honestly doesnt control me one bit. we joke around with eachother, and we play fight and stuff but nothing to serious. so anyways my mom talked to the teacher and my mom freaks out, so now I want to move out into my boyfriends parents house, they were gonna take me in once already, but since my family is litteratly crazy, there afraid of my family. im afraid my parents are gonna do something illegal, and that there gonna call the cops. im 16 years old, and about to turn 17 in less than 2 weeks. can a cop do anything about this? can my parents do anything about this? my parents say that its either living with my dad, or living with my mom, but not my boyfriends house. what should I do?
