My wife and I had to abort out 3mo unborn child due to complications. Now my wife is very upset with me and I don't know what to do. How do I console her?

See marriage counselor. Take her to the ob/gyn and reason with her. Pls understand that as soon as conception takes place, a woman's body is geared up for giving it's best for preservation of the unborn baby. There r physiological changes, where a woman feels the unborn as a part of her being. The bond gets created even before the baby starts to take shape. The brain sends out multiple commands to the entire body to care for, protect, feed, nourish and cherish the unborn baby. Your wife is upset bcoz deep inside the connection is still very strong. She can't accept the fact that something so fragile and precious can cause complications to her. She feels that she was to protect the baby and instead she had to abort. However today's world tries to justify abortion, it's still unacceptable on a conscience level. Empathize with her. Listen to her. let her shout at u, cry with u. Give her time. She will overcome it.
