Does divorce occur if the husband divorces his wife under duress due to her threatening to commit suicide?

This divorce is valid, and the wife's threat to kill herself is not taken into consideration, as this threat does not constitute coercion of the husband. Coercion is that which is directed at the coerced party (the husband here), such as threatening him with death or killing his child if he does not divorce. It was mentioned in "Asna al-Matalib" that the coercer's statement, "Divorce your wife, or else I will kill myself," does not constitute coercion.
