We became friends at first, then I started dating you, even though I was still with him

Honey, do you remember back when you and I first met? I was dating another guy, and then you came along. We became friends at first, then I started dating you, even though I was still with him. Knowing you had competition, you tried so hard to woo me and to win me! But ever since I told you we were going to be exclusive, you've backed off, and you just don't do all the little things you used to do for me.

And that is why I'm going to start dating other men. Yes, we're married now, and I don't intend on leaving you. Yes, I still love you! But you don't take my subtle hints, and you don't even try anymore. Now you're going to have to. One of my other men might sweep me off my feet. When I have sex with them, they might be a better lover than you. So you're going to need to show some effort, or who knows what might happen?
