relationship advice?

hey ladies, so long story short I don't find my boyfriend attractive anymore. It feels like I get annoyed with many things he says and honestly he is quite racist and plain rude. He isn't the guy I thought he was. We've been dating for 9 months and senior year is starting September 6th, a day before his birthday and his birthday party is in exactly a week. Anybody who has gone through this? Please give me advice as I really need it :(
