Has she talked/have you talked to any counsellors or clergy over the loss of the baby? How does she know its "all cleared up"? What is you/her desires on children. How long were your stints? What other sadnesses has she experienced? What has she said about her sadnesses? Have you asked?
Have you talked about her schedule? Her lack of activity?
Pity me that the heart is slow to learn
What the swift mind beholds at every turn.
