Relationship problems?!

Okay so me and my boyfriend have been dating now for almost 7 months and right before our six months we started fight. We fight more often than usual now and I'm honestly worried. He is the love of my life (as of now... People change of course..) and if we broke up if be heart broken.. This is my first serious relationship and I want it to last. We usually fight over the stupidest thigs like other people that harass us. Like I said, stupid things. He is happy most of the time but I just get scared when he is mad because when he is we end up gfighting and they are brutal... Any suggestions??????
