How can football ruin a relationship??

I've been with my boyfriend for nearly 18 months now, we're both 18 and normally get on great. But we keep arguing about silly things like he wants to watch football matches constantly and doesn't understand that I don't want to. Then when I get upset that he'd rather stay at home and watch football than coming to see me, he gets angry and says I don't appreciate anything he does for me. I really don't know how to stop these arguments! please help?
