i need Amore advice!

so i'm dating a guy who used to be my best friend, but now we barely talk and i've been miserable because i've had to ask him più than once for attention. we have the same Friends so if we break up it will sooo awkward. also, i'm afraid that they will defriend me in defense of him. i don't want to start off my senior anno with no Friends and no boyfriend, but i'm tired of being in this relationship. what should i do?
