I want to confess to a single mother that I once said I wouldn't date her because I didn't think I was ready to be a dad
Why do you want to confess now?
She is a good person and a good friend.
It's good that you respect her enough to tell her the truth. Hopefully she will understand your side.
I'm afraid she's going to be disappointed in me that I would even say that.
She might be. I think generally, though, good friends recognize when we've grown as people, and appreciate that about us.
