My husband and I have a 12 year old son and suffered from 2nd child infertility. When he was young he asked emotionally and often for a sibling. Eventually, he realized how much it hurt and stopped asking. I live every day with insurmountable sadness and guilt. I feel so much loss for the family that I thought I'd have   and can't. Guilt because my son is growing up alone and will have to be without us alone. Also, I feel terribly alone as I am the only person in our circle that has this experience. Pray for healing and acceptance.
