He wants me to get rid of the guys I'm talking to?

So I met this guy when I was in high school and he asked me out and I said no, ever since then we've been friends and we've known each other for years, got very close and he met this women that his committed to and we're just friends, anyway I met this guy and we started dating and I told him that my friend said we wouldn't work out and we both laughed it off and said jealousy but when the friend was brought up again cause I had said goodnight to him it blew up and he told me to delete every guy that ever asked me out cause you can't stay friends with a man so yes I did get rid of the guy but how would I know which guy ever wants to just be friends or not , advice please?
