I'm still concerned about her not wanting a child. Some women (my wife) spend years saying they don't want children then get pregnant and it turns out they (she) truly do/did want children. Others though, don't end as happily.

This is something that you two really need to talk about. If she's just keeping it because she can't stand the idea of someone else raising her child, and not because she wants to nurture and raise a child of her own, then you two really need to talk.
