This is inherently the problem with following the man instead of a theology. In the end, all men if positioned between us & Christ as primary guide will fail us. This is why, for 2,000 years in the Catholic Tradition, and before that in the Jewish one, we understood that God gives us laws to follow if we choose it.
I’m sorry that this man whom meant so much to you hurt you. I hope you are able to find it in your heart to forgive him and not allow his personal choices keep you away from Christ, brother.
That is all.
