Lisa I'm sorry you are going through this hardship in your life. Trust in the Lord and don't lose faith in Him. My wife was going to leave me a few months ago and I never let fear enter the equation. Two weeks later she changed her mind and our relationship has never been better and our relationship with the Lord has been rock solid since. Praise the Lord he can heal all things. Even though your husband is the one pursuing this course it doesn't mean you need to give up on the marriage. I will pray for you and your family.
