I wouldn’t try and persuade him otherwise but I would like to understand why he is so adamant about no more. I also wonder about all these other families I see where the man has grown kids & didn’t want more but has had a baby later in life as the woman has none. It makes me question why they can do it?
Because it's a monumental responsibility, huge expense, takes time away from other valued pursuits, is physcially demanding and often quite boring/messy. Maybe he doesn't want to risk another child being high-needs, ill or otherwise extra demanding in terms of time and money. Maybe he wants to prioritizing saving for retirement, or just be free to wake up and do his own thing on weekends.
Maybe he's concerned about the environment and doesn't want to contribute more humans.
I really don't think it's on to press anyone to come up with a reason for not wanting to procreate. It's just rude and implies that they NEED a reason, which no one does.
What if you leave him, never meet anyone suitable, and end up childfree AND without a relationship -- or a single mum by choice via donor, and the child is high needs or difficult and you're skint and burned out and have no one to rely on? Would you really prefer that to being coupled and carefree as you head into your 40s, 50s and 60s?
To each her own but it sounds as though you should not waste any time leaping into the dating pool aggressively and seeking a different mate who is enthusiastic about becoming a parent.
