This is a hot topic for my wife and I right now. We've been married for almost 15 years and have three beautiful children. We've had our arguments just like any couple but, generally speaking, we have a good marital relationship and we're best friends. 
 
After we had our first two kids, we decided (mutually) not to try again for awhile for various reasons (moving, job changes, etc.). But then, she told me she wanted to try again "just one more time." I was resistant at first, not really interested in having more kids, but since she said "just one more time," I figured it was something I could do for her because she wanted it so badly and I loved her and wanted to make her happy. So we had our third, a boy, in November of 2003. He's beautiful, and I love him to death, and even though I really wasn't interested in having any more than the two kids we already had, I feel no regret at all about having our third. 
 
So after we had our third, I'm thinking we're done, because I feel like I'm done, and she told me she would be done. So when our third gets to be about a year and a half, she tells me she still wants another one, and that she was lying to me before about being done after three. We fought about it like we've never fought about anything before for about two months until I finally gave in and she got pregnant again. I was angry for feeling deceived and coerced and couldn't emotionally connect with the baby in utero. My wife was conflicted, too, because she was happy to be pregnant again, but knew I was disengaged and unhappy about it, even though I consciously treated her well just like always, despite being angry with her. 
 
Tragically, in November of 2005, we lost the baby in the 23rd week of pregnancy to Trisomy 13, a highly rare, fatal genetic disorder. We were both greatly saddened, but my wife was deeply, deeply heartbroken. She wanted the baby so badly, and she also knew that, given how much I fought her on it, it was probably going to be her last chance. We have grieved the loss of that baby, and we're all individually healing from that experience. 
 
Unfortunately, it seems to have strengthened and intensified our opposing positions on the issue. She wants another baby even more, now, and I'm more averse to the idea than ever. She's been bringing it up, and I've been mostly just skirting it, because every time we try and talk about it, we just end up at the same old frustrating impasse. It's seriously threatening our marriage and family now, and I just don't know what to do. 
 
I feel like I'm doing everything right as a husband and father and just being punished for it. She treats me poorly regularly because she's angry with me, even though I'm doing nothing wrong. When she was pregnant with the baby we lost and we didn't know we were going to lose her, I treated her just fine, even though we both knew I wasn't happy about being pregnant again. It's not like we've had fertility problems and haven't been able to conceive; we have three kids. It's not like she's never had the experience of being pregnant and having a baby to care for before. 
 
Anyway, it feels like it's coming down to a deal-breaker for us and I just don't know what to do. Today she said to me, "When the kids grow up, I'm going to divorce you and adopt a baby." She said she was just "alerting me to what she was thinking," but, I'm convinced it's just another attempt to try and manipulate me into complying. She's been saying lots of cr*p like that to me lately. I think how she's treating me is so unfair; I can't help that I don't want what I don't want. But on her side of the coin, I can see how she could be very frustrated and angry that she's not getting what she wants. 
 
I don't want to break up our family because our relationship is otherwise very good and we're truly best friends. We have one of those rare kinds of marriages where we actually see eye-to-eye on most things and it actually works in its own weird way. The kids are great, good-hearted, well-adjusted kids and I'd be afraid of what might happen to them if we were to get a divorce, having come from a broken home myself. 
 
If anyone reading this has any advice or insight to share as it relates to our situation, please share. I think we're almost at the end of our rope, and could desperately use the help and perspective of anyone who can help. 
 
Thank you.
