Option a and b aren't really possible. Option c is possible but I have a good/stable job and I don't think it would make sense to leave. Is it really impossible to resolve this relationship?
In marriage..... and temptation is at work then quit your job and move away...take this serious. Your wife should be your close female Friend. Maybe you have your priorities confused ? saying this with a sincere heart, pointing things out maybe that you haven't thought about before.
Put God first in your marriage. Maybe try reading the bible together with your wife, praying together, remembering bible verses together. This will help build up better communication. If your unhappy with being married? committment is about being willing to be unhappy until you work it out together.
Love does what is best for everyone.
One of the characteristics of a person with integrity is keeping clear of temptation.
Psalm 105:4 Seek the Lord and His strength; Seek his face evermore.
