Bereft

We'd been married seven years, and for the most part, I thought we were happy. Little did I know my other half wasn't. He'd been screwing around on me for the past six months. Now, on the verge of divorce, I've found myself in a conundrum.
He's half my age, with a body that won't quit. I keep telling myself it's payback, but who am I kidding? Instead of getting even, I've now made things irreparable. I have a choice to make, and it's going to be a lot harder than I imagined.
