I think that your fiancé's opinion is as important as yours and needs to be equally respected. Ask him why he doesn't want more kids, at the end of the day you cannot force him! It wouldn't be right
It’s valid for you to be upset, and it’s a bit harsh that he suddenly just made this decision, but it is his body and his choice, you can’t force him to want to have another child, just as if it was the other way around x
It’s fine to be upset, but he is allowed to feel the way he feels and take control of his bodily autonomy. People are allowed to change their minds and often do after the reality of children set in. That’s not to say they don’t love the children they have, but that they understand the immense responsibility in a way they didn’t before. I used to think I wanted 3 kids (and my husband would like one more), but after having a traumatic second birth and the exhaustion of 2 under 2, I have decided I’m done. He was a little disappointed, but he respects my decision.
He's right though , it is HIS choice. If you were a man posting this then the comments section would look very different. Him saying he finds parenthood tough or is worried about money is a good enough reason, he shouldn't have to explain himself more than that. As for family, who cares!
I think it’s fair to upset. You guys are a family and that should be a decision you make together. Did he ever express to you that he didn’t want a big family? Or he also was originally in agreement to having 3? I’m sure that’s hard on you regardless and you’re allowed to be mad/sad.
