That’s stupid like can’t you talk about your things to more than one guy friend?!  I hate the type of boyfriends that like snooping in to almost everything that their girlfriends do, I mean as long as he has trust in you, why push you away by spying and becoming nosyy ? And in your case, he’s not even your boyfriend so it’d be pretty stupid for him to tell you who you should or shouldn’t talk, if he feels really jealous, let him deal with it, its not your problem. This really reminds me of back in the days in middle school as kids, pretty immature. You don’t just stop talking to people because your friends don’t want you to, you pick your friends and what you want to do. And if you’re this really outgoing person and you being his friend, he should know you well and put up with that kind of attitude. Its funny we usually mistaken guys for not being like a dramaqueen or socializing much but they are the ones that love to talk  to their guy friends about their friends or girlfriends behind their back and get  jealous and start fights!! if he thinks you're also in love with him, don't hurt him by keeping him in this love delusion, now be a lady and tell him that you DON'T like him as a boyfriend and stop tellig you what to do! common sense, honey.
