Clambake, as a woman who suffered almost 13 years of infertility, I understand your frustration and resentment of someone who didn't want her baby but didn't give it to a couple who desperately did. Unless a couple has experienced this emotional hell there is no way to adequately explain what it entails. Unless a couple travels every avenue they can afford to become parents only to be told there are no babies available to you due to the blood issue, unless you attempt private adoption, fall in love with the baby girl only to have the mother change her mind, there is no way to describe the agony.
I DO get it and I am delighted your wife is pregnant now. I wish your growing family the best.
