Your friends are part of your life. You should be able to bring your boyfriend over and hang out peacably any time you want to! I can imagine it creating some rifts when you want to go hang with your friends and your bf wants to go out and have fun too.
You guys can't go to movies together, or the fair, or amusement parks, or out for a picnick, or have house parties/get togethers, celebrate holidays, or birthdays, or ANY of that stuff together simply because your boyfriend is homophobic!
I broke up with my fiancee for a reason such as this. He is very anti-military and has a completely different view of it than I do. He even went so far as to say I was "not smart enough" to join NASA in his attempt to dissuade me from joining the Air Force, and said he would not marry me if I did join. That was a relationship ender for me.
