Don’t give up hope! I know several kids who have wonderful step-dads, my grandkids, among them.
I have hope tempered with a healthy dose of realism.
Was your grandkids birth dad an abusive SOB?
It is the repeated hookup with abusive men syndrome that so many women have that I was pointing out.
Not all divorce stems from abusive men. Some men are just selfish twits others are philanderers. Some women are the same.
