Partner said something upsetting

[MarketResearch90]

I’m 39, partner of a year is 46.
he has twins who are 5 and was with his ex around 2 years.
He was up for having a child with me and I thought if it happened it happened. I always thought I’d have them but have never been particularly maternal or longed to have them. Just saw it as a thing people did really. I’ve seen how my sister struggles with hers and don’t feel really it’s entirely for me

Partner hasn’t gone on about having children or anything at all as he has two of his own already so it shocked me when he said that women basically aren’t doing what nature intended by not having children, that animals procreate to keep life going and it’s a woman’s duty basically to do this. He found god a few years ago as it helped him overcome addiction issues and what he said maybe had religious connotations.
it made me feel really rubbish and inadequate compared to his ex who I compare myself to a lot since they share something me and him don’t.
this happened a few months back but I keep going over it in my head.

"animals procreate to keep life going"

Biology grad here. He's clearly never heard of bees. Or meercats. Or W D Hamilton's theory of cooperative fitness.

Not all animals are meant to produce young for themselves and, as a 'k-selected' social ape, neither are all humans.

Are you still with him Op?

So by his own logic, is he suggesting that nuns are going against God’s will?

Addiction plus "found god" how much bigger red flags do you want!?
