My husband is losing faith

And I feel helpless to help him.

I cant tell him why God let us be born of abusive parents (bother of us but different families states away)

I cant tell him why God made me with a chronic disease at 14 years old that makes me have agony every day (lupus, fibro & others)

I cant tell him why God made it so unfair for him to watch the suffering of his beloved wife with health scares, hospital visits, etc.

I cant tell him why God brought our 3 little gals home before they even got out of the second trimester. Hes lost three of his children in a short amount of time without ever holding them.

This last loss has really broken him.

I think he feels lost because he was trusting in God to heal me and was even prepared for miscarriages related to my condition... but these miscarriages have all been chromosomal and not linked to my conditions. I dont think he was prepared for us to have issues miscarrying outside of my condition.

My heart is breaking for him. I've tried to leave the subject alone because that's what it seemed like he was needing, but now I'm not sure.

How can I help stoke my husbands faith and help him come back to God, who I think he is questioning because he may blame for this or be angry at for this
