Suggest Treatment For Uncontrollable Ad Excessive Cussing

My husband is a retired, medically disabled veteran who can t seem to have a simple conversation without using cuss words. He does not understand how his language turns me off , as well as offending me, so our sex life is almost nonexistent. We have been married 35 years. I ve tried getting him into counseling and he did go twice, but didn t open up to the Dr. I let him go in alone but if there is a next t in me I think I should go in to session with him. Any thoughts or advice? He is supposed to be a born again Christian but his language sure doesn t show it.
