He accidentally fucked up with his girlfriend or wife or something, and she left him. And he loves her more than life. He's saying that he'd do anything to get her back and that any amount of time without her is horrible, a few minutes or a few years.
"I wrote you a thousand letters all inside my head" I've personally experienced what I believe this is saying. When you want someone back, you're afraid to say anything because you're afraid if it's even slightly wrong that they'll hate you even more. So you keep going over what to say in your head, but never actually know what to say.
Once again, it's obvious what this is about.
