Am I being to sensitive

I was in a really dorky good mood a few days ago and my boyfriend flat out told me I was being annoying. Which was fine at first because we both laughed and what not but later on that night he said it a few more times more seriously and for the past day he has been a little distant and the "I love you" seems empty. I don't know if I'm being to sensitive and over analyzing or if I should be worried
