No, it is possible, it is just unfortunately very rare. My ex is a nearly perfect father to our daughters. And back in his prior marriage when he had another pair of kids, he was a pretty good father too, although not as nearly as good as wisdom and dedication came with age. The sad thing is, the kids take it all for granted. Maybe one day they will realize how lucky it is NOT to be a victim of CSA, but right now they are sometimes mad at their dad for that he is not some corporate big wig like some of their classmates' parents. They do not realize that he made a choice to stay with them and that decimated his career. But they are not always mad, more often they are affectionate with him and the younger one is especially supportive - she would cook dinner (at her level) if he is feeling sick, for instance. I hope that as they grow up and get exposed to other people and their stories, they will appreciate what their father has done for them more.
