snapcrap
I'm really surprised at the amount of people telling you you are being unreasonable OP! You are absolutely not.
Clandestino
It takes two to have children and if one side doesn't agree with more, you need to stick to it.
I agree snapcrap and I dont know why Calndy thinks the wishes of the party who doesn't want children should trump the wishes of the one who does, especially when he initially agreed he would have more and is now reneging on that.
I am very suspicious of the OPs husbands motives.
IMO when men are unwilling to have another child (espcially just a second) it's often because of discontent in the marriage. That's not to say he's already having an affair, but I suspect he's thinking about it. Do you think there could be someone on his radar flirtygirl?
To the poster who said her mother tricked her father and had a second, then her dad left within six months I would say my money would be on the likelihood he was planning his exit anyway. Maybe her mum did the right thing and got the second child she wanted first?
The choices the OP has;
Accept - risking he leaves her in the next few years and goes on to have more children with his new partner while she has wasted years of her precious narrow female window of fertility on him. Or even if he stays a lifetime of bitterness.
Present him with the choice, he agrees or the marriage is over. This will be very revealing
Trick him, just get pregnant, but be prepared for the fallout.
Tell him its over, you want different things from life and he doesn't love you enough to care about your happiness or even to care about giving his child a sibling (unless of course he plans a different mother for that).
It is NOT unreasonable to want a second child, wanting third and fourth are an entirely different matter as that is creating a 'big family' when issues of expense, size of home even car, also begin to impact.
