My Response To What If Christian Wife Refuses To Submit To Husband

I received a question recently that I have decided to answer with a video message.
The questions I received reads,
"What about a wife that claims to be a Christian but refuses to submit to her husband. 18 years of marriage I feel I am loving her like Christ loved the church I am suffering and loving even though she is not doing what is commanded to submit to the husband in everything and often has fits of rage and hates this command. I need help and want to leave her as she is not encouraging me but tries to bear my spirit down and constantly points out what she considers flaws. I am commanded to love her she is commanded to respect me that is the word of God I feel she doesn't like this rule and is rebellious. I wish god gave a way for divorce from this as she is becoming a thorn in my side and the enemy uses her. Advise?"
