Why must everything go back to "Frank is no good"?
When I read this, I thought that all she was saying was that the girls needed their mom. No matter how great of a dad you are, a girl still needs mom!!! It isn't about you not being good enough. It is not about you at all.
I think the point of that post that didn't come across very well was that I recognize that I think these crappy thoughts and I need to give myself credit for doing 'good'.
So I agree with you. It doesn't need to be that way.
