Sherlock,
I, too, suffer from the same question. As a matter of fact I came to MB to find an answer to this question. Of course I received some good advice but there isn't much others can do to remedy this problem.
My wife still feels the need to have more children. I am finished. My reasons are similar to yours.
What is even more difficult for me is that my wife has some of the same reasons as I do for not wanting more. She just gets real depressed when she hears the words 'we're not having anymore kids'. I think in her case it is an issue of how she defines her self-worth. She's thrown herself 100% into the 'mother' mode and she is a wonderful mother at that. So she defines herself as a mother and finds comfort, respect and a feeling of worth doing just that. Unfortunately it is at the expense of everything else that she throws herself into this mode. For awhile and even occassionaly now and then our relationship has been and is suffering because she forgets about us. I've been communicating to her her need to become, once again, something more than just a Mom. She is a beautiful woman who has a lot of wonderful qualities and I let her know it constantly. She's been making some changes and things are getting better for us. As you know marriage is a journey and we seem to be moving toward a common goal.
In the meantime the topic of more children is being ignored. I'm hoping there will come a day when she agrees that the logical reasons for not having more kids far outweighs the emotional need to have more.
Does any of this ring true for your wife? I'd like to hear more about your situation.
Here is a link to my initial post on this topic.
