velveteer, you were getting so much great advice that I didn't see any need to jump in.
Now, I hope I can give you a measure of comfort. You are much better off being honest about how you feel and allowing her to move on to find someone who has the same interests as her in having a child.
I married my STBXH at 36. I held off having children, but had decided that I would do artificial insemination at 38 if I didn't find the right guy and get married.
Before getting too serious with my STBX when we were dating, I addressed the children issue. He had 3 biological children already and it was a concern for me not to waste time with someone who didn't want to have a child with me. He wholeheartedly agreed that down the road if we were became more serious, having a child was on the table.
Before I said yes to his M proposal 2 years later, I brought the subject up again. Again he was 100% for us having a baby in a few years after solidifying our M. Two and a half years after M, I was ready. I brought it up. He, at first, denied ever having the conversations. But then he admitted that he never really wanted to have anymore children. I'm Catholic. D wasn't even an option for me, maybe annulment, but at that point I was so in love with him and his children, I couldn't see going that route.
My STBXH has been selfish in everything since the day after we got M.
I wish he had been as honest with me as you were with her. One day, she will thank you. You will also look back and be glad that you didn't selfishly hold on to her. You did the right thing. I'm sorry that it hurts right now. Sometimes the right thing to do isn't the easiest or least painful.
Peace and hugs!
