I just want to do it right, God's way.

I am in a situation whereby I strongly believe that I have a spiritual assignment. Since March this year I have been doing all my best to find myself so that I can know for sure what I need to do. I have been going through some material that I downloaded from gnosisteachings.com and it all makes so much sense.
Problem is my marriage is falling apart and I just cannot be derailed from this path that I believe to a certain extend is a spiritual calling.

Question: Do I let go of my husband as I strongly believe he is completely against this call of faith and will never agree to, especially, chastity?
