So this week we found out for definate that we will never conceive a baby naturally or have a baby that will biologically be my husbands. We have opted to have

with sperm donor. Has anyone on here been in this situation and how has their husbands dealt with this? He feels that he will not be able to bond with baby when the time comes...

Edit...he is 100% on board but obviously has his concerns. He had cancer as a child and has 0 sperm. We have talked until we can talk no more about our options to have a family. Ive told him ar any stage he cant cope we can stop the process at anytime.
