I’m very sorry that your and your family’s life has been so full of suffering. And I know that there are lots of people in the world who blame having a large family for causing suffering - but I just can’t help but think there must have been underlying problems that were the real cause of the difficulties. If, for instance, a husband is being demanding of sex with no care for how his wife is feeling and being insensitive and unhelpful if pregnancy results, that is an indicator of a deep rift in the marriage. There is still at times some cultural misogynism baggage in some cases that encourages insensitivity.
Please accept my prayers for your family and all families for whom having an abundance of children has been a challenge and yes, perhaps more bitter than sweet. I know that we can’t gloss over and pretend those situations don’t exist. The objective moral issues surrounding contraception remain what they are, but sometimes a woman is so frightened and stressed that maybe her guilt is lessened, and God would have mercy on her.
We must be careful not to put words in the Pope’s mouth, though - the press does quite well with that, unfortunately.

Just a reminder, not trying to be harsh about it. And again I will definitely pray for continued healing for your family in all ways.
