Is this a valid reason to breakup?

My boyfriend of 6 years decided today that he feels that we have no common interests. We both are in medical school, like watching tv, same religion (different sect) and same ethnicity. We both like to fuck lol I like to sing dance play violin. Big girly girl. He likes video games and watch anime. I watch anime and play video games with him when he wants. I never thought having different interests means we are not compatible. Do you guys?
