idk what to do...

Hey guys, so I've turned 16, 5 months ago, and I've met this boy last year September, we are still together but I'm afraid because my mom doesn't allow me to date yet... since we been together I've been sneaking to his house and sleeping over, I'm scared to tell my mom but i know I'm not gonna like her reaction, and I'm scared to get caught because I don't think I'm gonna be able to see my boyfriend again. My mom isn't the type to have conversations about sex and boys with me, idk why but that's how she is. I have 2 brothers and my oldest found out what, but he doesnt know where I go and if I'm still going there. I want to tell my mom "I like this boy" but idk how she is going to react, if she doesn't accept it I know she is gonna start thinking that I go over there, and I might not be able to see him again, and if I get caught its gonna be worse and I know for sure I'm never going to see him again, im thinking about telling my mom in the summer or in may, I don't want to keep sneaking around I want to tell my mom everything but I'm scared, idk what to do
