Boyfriend says he's getting annoyed with me?!

Lately all my boyfriend says is how annoying I am making him. I'm starting to feel really insecure. We've been together for almost 2 years, he lives with my son and myself. He's a great role model for my son and treats us really awesome. We've had our troubles but lately I can't help but be so insecure. I need some advice and maybe some motivation.
