in which the husband didn't want kids, but the wife fell pregnant accidently (on purpose)...

Now this could have gone two ways. He could have felt like she had betrayed him, and caused him to pull away in the end anyway. Or like in this case, the husband was surprised, by the 4th month of pregnancy, he was so in awe of what was taking place inside his wifes body, that he absolutely fell in love with their daughter before she was born. He worships this little girl now.

But, as I said, it could have ended very badly, with him leaving the wife, and her having to raise the little one on her own.... almost a punishment. Obviously in these cases its probably better than being in a family where your father didn't want you anyway... and makes you feel that way for the rest of your life....
