Taff, you poor darling. I'll be thinking of you and your angel.

I hope you can talk to your DP about this, as the other girls said, men don't do good responses! And if he did mean it, point out that placenta-building is coded by the male gametes, so it's all HIS fault (I agree that no-one is at fault, but I also think he has no right to think like this over the loss of a baby).
