You single dads may feel stupid for treating your ex so well when so many men don’t. But you are not stupid. You are amazing. It’s hard, really hard. Men need to cut all ties when moving on from a relationship and you can’t do that when you are a parent.
At least not if you are a good one.
To the one’s that stay, I admire you, and I thank you for setting such an amazing example for your daughters, and especially your son’s. They are watching how you treat their mother.
