I would bring this up with your W only if it's a deal-breaker for you, other wise I would never bring it up to your W again. She knows your feelings and if she wants to have a child she will bring it up.
Love yer for thee person she is, not at the potential mother of your children.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
