So me and my boyfriend have been on and off kind of for the last two years. With our recent break he became friends with the girl i was worried about during the relationship and i found out they both had a thing for each other. they never got together during our break but there was some flirting. he claims they’re just best friends but i don’t like them being around each other bc i’m scared that somethings going to happen. i know i should trust him, but like, i don’t & whenever they hang out i get upset because i hate that they’re friends. what do i do? :/
