My youngest is 2 1/2 and I still have feelings about never being pregnant again. My situation was a bit different...I had fertility problems before ds1 and he wound up as a emerg c-section. Got pregnant with ds2 quite easily, and he was a scheduled c-section. We talked for a long time about getting my tubes tied. In my mind I knew we should stop at our wonderful, healthy 2 boys, and I was already 35, but in my heart I always wanted a girl and deep down I knew I wasn't ready.
Even on the morning in question, I hesitated and asked my then husband if we really wanted to go through with this and he insisted. He never offered to get a vasectomy, and I just opted for getting my tubes tied because it was a scheduled c-section and the doctor was in there anyway. Little did I know then that when he said he was done having kids, he really meant that he was done having kids with me. He had started another life with another woman when I was 4 wks pregnant, and was already planning to leave me for her. We split up when my youngest was 6 weeks old, and I found out about his affair shortly after. They plan to have more kids together.
I am getting through with great support from family and friends, a great counsellor, and of course my 2 boys. I have let go and forgiven almost everything, but in my heart I know I will never forgive him for pressuring me into tying my tubes. I loved being pregnant, loved having little babies, and with both my boys I feel like I missed out on their babyhood due to situations with him (we had some struggles after our first dh too), and I can never get that time back.
So, yes, it is a grieving period, and although in time it will fade, I don't think it ever truly goes away. It's yet another one of those things that only a mother understands.
