It may sound trite to say never say never, but I've always found it to be good advice. I think it's normal for even the staunchest attitudes to change, as circumstances do. When my husband was dying-- when we decided to freeze his sperm-- I think I believed, at least in part, that I'd never remarry; as time went on and the grief became less overwhelming I've reconsidered that position. As an example.

I can see how being here might bring up the issue in an unfamiliar way. It's interesting, how the curses affect us in the long term... Obviously becoming a parent isn't a decision to undertake lightly, but I don't think there's anything wrong with being open to the possibility. Even if you ultimately elect not to.
