Boyfriend vs Family

I’ve fallen extremely hard for my boyfriend. I am 19 and he is 28. He’s a great guy and owns his own business but he has a slight hiccup in his past where he got caught with weed in his truck and was arrested. He has 6 months and all the charges drop. However my mom can not get over this fact because “people in drugs always stay on drugs”. I proceeded to tell her about the 6 months and the charge drops but then she was quick to say even if he had a past white as snow, he’s still 28. My mom has given me a choice that she will take everything from me (car, phone, school) but my boyfriend would be able to support me and knows how important school is and we’ve talked about how we’d handle the situation and he is completely ready for me to move in and him be my “main provider” even telling me he’s going to the dmv on Tuesday to get his second car in my name to drive, and is ready to switch me into his cellphone plan. I am at a loss because I live my mom, so much! But if she is going to continue to not even let me talk to him and threaten pulling everything, is it just time to move in with my boyfriend? We realize it’d be hard but financially he is very stable. Any input would be really appreciated!
