I married my husband while incarcerated. We never had counseling nor have we had any mediation And he said when we argued, his mind went back to prison, him feeling like he may hurt me because he felt disrespected by the words being said during arguments and that he did not want to be without me. He just didn’t know what to do so he pronounced divorce.
The divorce is not valid because of the anger.
Moreover, according to some jurisprudence (Jafari) these 3 or 4 divorce should be in different times or sessions . In one session it is considered one divorce even if he says "I divorced you 3 times".
