Why is it always, "I'm Fine"?

Trivia

Are there any other people out there that get this response from their spouse when they ask if they're okay or if you ask is there something wrong? My husband hates when I ask him either of those questions repeatedly. But, I can tell he's in a mood or that he's not truly fine. I'm not doing it to annoy him. I sincerely care if he's actually okay. Sometimes I follow it with, "Did I do anything?". Because, I CARE and if there's something I've done to upset him, I'd like to fix it. I want us to have open communication. We've been together for 13 years and married for 7 years. This has always been a struggle because I like to talk about things and he doesn't. So, how do we meet in the middle?
