my cousin and his wife got married 2 years ago, she has made statements that she doesn’t care if they get pregnant or not and they are very faithful Catholics, now, what I know and what most don’t know, she has had severe indometriosis, she has had surgery done 2 times to remove it and seen several doctors who have said the chances of getting pregnant are slim to none, now, it is easier for her to say she doesn’t care than to admit, yeah, she cares and she is hurting so awful inside but she has this tough outside, of course she wants kids but she is trying to keep the pain from being too bad if she can never conceive, I have friends with the same dilema, they can’t get pregnant after trying for 6 years, so, they act like they don’t care but believe me, they do care.
I don’t know many true Catholics who are really childless by choice unless they marry very late after 45 etc.
I think that Catholics who say they are childless by choice may be saying it but in their hearts that is not the truth.
Just my 2 cents
