boyfriend problems

my boyfriend and I have been together over a year and a half. It seems to be that I'm more interested in him than he is with me, but people say that's crazy as they say 'anyone would love to be with you', that still doesn't convince me though. Anyway he has came up with 3 excuses in a row that he can't see me so I don't know if I should say something or maybe I'm just over thinking it, help me please..
