I did feel the "pangs" of not being pregnant, and it was hard specially when my wife was pregnant. I was soooo happy for her, and for us, but it was so hard on me. She never knew just how I felt. However, after the kids were born, I was the best "Mommy" in the world; feeding them, changing them, baths, and just loveing them so much.
I gave them -and still do- all the affection I never got, and you know what, it did help me 'heal" for all the abuse and neglect I suffer as a kid.
