I am in my late thirties and I want a second child and my husband does not especially since he has one from a previous marriage. I am sooooo upset and he is firm with the decision.

Hard choice, since there is no good equal ground. Was this not something discussed prior to marriage?

Are there any other reasons he doesn't want to have another child other then he already has two children? Can you afford to have another child, now this can mean more then just financially, it also means being able to give adequate time to each child and also being able to emotionally give to each child. Also with another child will you still be able to give of each other to this marriage. You may want another child, but have you stopped thinking of how mean you husband is being not wanting another one to really think why he may not one. Being selfish isn't always the one not wanting to have another child!! Good luck

Better to be upset, than resented by your husband.

There is nothing you really can do. You can except it or if not, and it is a deal breaker then end the relationship.

People are at different stages in life and this decision needs to be made together as a couple. If not, and it can not be dealt with then time to move on.

But in all fairness you can not make somebody have more children then they want. If you want to stay in the relationship then it is time for you both to seek out couple counseling.
