I think grief is universal. So you would grieve this loss the same way that you grieve any other.
It takes work... specific work pointed toward a goal of peace and resolution. You have to want to work at finding resolution. Stop blaming your roadblocks, stop dreaming of what if's and what might have been and come from a place of acceptance. But part of getting there is WANTING to get through the process.... and that's where lots of people get stuck. Because they want a measure of control that just isn't realisitc or possible.
It also takes time. Meandering time where you just "are" with how you feel in the moment. Where you dream of what could have been, might not have been and wish that it would be's.
I also think, that because in your case you and hubby are not on the same page, you also have to add in "forgiveness". You need to forgive your husband for wanting something different than you. You need to forigive yourself for holding a grude, or not trusting him or not putting his needs equal to your own, or..... whatever it is YOU have done. Because you've done "something".... we all have.
I had it "easy", I guess. I could only be mad at Mother Nature or my own stupid uterus. There wasn't someone living and breathing in the house next to me that I felt had "done this to me" - which can wreck a marriage. So, I urge you to tread lightly with hubby. Recognize that loving someone isn't about how you feel about them.... but about how you ACT toward them.
I also think (and I tread lightly here, because I'm going to come across as judgemental) that sometimes if you aren't on the same page with basics, you can be adversarial about almost anything.... just because. Hubby may not want a 2nd one because he feels another one would strain your marriage or take away too much time from the one you have. But, if you give in to him LOVINGLY and WILLINGLY on some of those things [like dessert and sausage :-)] you might find he softens in other areas as well. And you can't do it in the "bargaining stage" - as in "I'll be a better wife if you give me another baby"..... that won't work. But you will sometimes find that if you are more willing to support him (the general "you" and the general "him") in all his craziness that he is sometimes more willing to want you to have what you need as well..... that's how marriage was intended to work. you EACH make sure the other has what they need.... even if goes against what YOU think you need.
I'm rambling........ I hope that you and your husband find peace in all your decisions.
