He is humiliated to have you know the awful details of his financial mess. I do not see a way around that... Exposed lies make liars defensive. You have offered him your heart and loving help. I would think it is time to act as if you love yourself.
I guess you need to go cold and do what it takes to make yourself and what is left of your dream, safe. Include your new YMCA and maybe your minister in your wellness plan. I know how painful and sort of tragic this will feel. Feels already.
It will feel terrible for awhile. Forcing this confrontation may be the real solution. Not cooperating with his lies and disrespect will create more anguish temporarily, but eventually provide relief.
