there is no Scriptures that teach you must be IN LOVE with your spouse, Scriptures teach that you are to love your wife, you don't have to be in love with her to fulfill that Scripture. you should stay because God hates divorce. You made a vow, keep it. Unless there is sexual immorality on her part. Put it in your head now, that you will grow old with her, she is yours to keep until you die. put out of your head of having a better life with someone else, someone that you will be in love with. God will bless the marriage your in, if you do what God wants you to do. God never wants a person to divorce. God will always test marriages to see if they would be so easily persuaded to throw in the towel. God blesses marriages that fight to make the marriage work. Talk to any happily married couple who have been married for many years, they will all tell you there was a time they wanted to get a divorce but stuck it out, These are the marriages that God will bless in due time. Love you wife like are are instructed to do as a good Christian husband, love her like you love your own self. Then see if years from now, you are not happily married and God will bless your marriage. But as long as you think divorce is on the table you will always be looking at it. Take it off the table throw it in the trash, then take out that trash and burn it, so that it never comes up again. She is who you are always going to be with until you die or the rapture comes, make it work, When God sees that you are trying to make it work, that is when He will step in and help your marriage, but if you always have that divorce, or that attitude the grass may be greener on the other side, His hands are tied from helping your marriage. Do what you are suppose to do first, then God will help you.
hope this has helped in some way.
