Go back and read my post. Detaching doesn't mean that you stop caring. It just means you don't let your emotions get tangled up with your WAS's. You continue to live your life.
You wanted to be married. You got married. It doesn't matter that you're single now or that you like being single, etc. It wasn't in your plan to BE single. You wanted to be married.
It's human nature to want what they can't have. She pulled the rug out from under you, so you were left shaky and uncertain. It happens. This wasn't your choice but hers. That's why you feel the way you do. I've been there.
