College & relationship opinions please:)

So me and my boyfriend haven’t been dating for a super long time, but we’ve been best friends since we were 12. We both had secret feelings for each other the entire time (5 years). I got stuck in an abusive relationship my freshman & sophomore years of highschool, i finally got out of it and had time to work on myself as a person. Me & him are both juniors now, about to be seniors and we’ve been dating for almost 5 months now. I realize this sounds like a premature thought or step in a young teenagers life but we are both 17 and i have already received an offer to a college and i can’t picture my life with him in it. he has never treated me any less than a princess and would never treat me bad and we talk about our future all the time. but basically after graduation and us both being 18, almost 19 by this time, would it be a bad idea for him to move to kentucky with me when i go to college? and if not, how would i tell my mom?
