I think what worries her is that she isnt sure she will ever want a baby with dh. Not because of a lack of commitment, but her dh (who she still has a relationship with) would be devastated and her family would disown her...but at the same time she feels a strong biological and emotional pull to have another child (as do I). she also doesnt feel comfortable having a child with her dh because then the child would be raised in a different house from its father knowingly and on purpose.
Figuring out the having of more children seems to be a big issue for us right now.
btw - negative pregnancy test.
