@elainer12 Perhaps you could approach this rabbi and ask him for a referral to someone you could talk to or zoom with? You needn't reveal the nature of your issue, nor that you suspect he may not be able to separate himself and his closeness with your husband's side of the family from your needs for him to be both circumspect and respectful...but if he just acts in good will and gives you a couple of names of potential allies/confidants, then you're ahead.

Is there no 'help line' established by the rabbinate where you live that is published and that serves people with your very circumstances?
