Your husband loves J and has not given up hope, hence his disappointment in J. you have detached succesfully other than how husband's behavior affects you.
so, when J got out all he could think about was getting drunk. he did now and will face the music. each time he learns from his actions. like your husband I do not give up on J.
if his PO finds out he was drunk it may cause havoc for J.
meanwhile J is not the first to get out of jail and get drunk. the spirit is willing but the body is weak.
