Boyfriend loves to pick fights?

My boyfriend has over 1,000 Facebook friends most of them being girls and I did have a problem with it when we first started dating because of the girls he would add?? He also always hides his phone from me and never lets me even touch it?? Today he made an Instagram and he was looking through I follow and asking me “who’s this” with any boy who I follow, and making faces and I know he got jealous over that?? I can’t follow one boy but he can have all these girls on his Facebook?? Double standards
