Does a divorce occur with the statement, "I will divorce you if you do not reconcile and do what I want within the limits of Allah's Sharia," after the wife improves?

It is understood from the question that the questioner threatened his wife with divorce unless she changed her ways. This is neither a divorce nor a suspension of one; rather, it is merely a threat. If the wife’s condition improves, she should not be divorced, and the questioner is not bound by anything from his threat.
