I couldn't do it, really.

Have you seen "Men of a Certain Age" yet? It's on TNT, starring Ray Romano, Scott Bakula, and Andre Brauer. It's funny, but it's really dark, too. I wasn't expecting that. It is the kind of show you kinda wish you could stop watching, even while you can't stop watching.
Ray's character is in the midst of a divorce, and watching him interact with his ex-wife is tough. During scenes like this I picture them on their wedding day, so happy. I imagine how sure they must have felt about each other that day.
But the thing that really gets me is this: how do you separate from someone who knows you so well, who you know so well? Even after only 8 years of marriage, I know Scott so well. I know he can't keep a secret, I know how cranky he gets when he's hungry. I know what makes him laugh, I know how emotional he is. I know how he'll react to things. I know he wakes up happy... well, you see what I mean, I KNOW him. Intimately. And he knows me, like no one else does.
How do you live with distance between you and someone you know so well?
