Top 15 Ways To Mess Up A Marriage

1. Have Premarital Sex - This can be with your future spouse or not. Regardless, the statistics show that it means a much higher chance of a failed marriage.
2. Cohabitate - This doubles your chance of divorcing your spouse well over 60%! Go with this one if you almost certainly want to mess up a marriage.
3. Cheat on your spouse - This can be with a real person or with porn. Either messes up a marriage.
4. Drink too much or use drugs - This one is a great way to love a thing more than your spouse.
5. Marry a non-Christian - Now, there are certainly marriages that succeed between believers and non-believers, but at the least you are putting a big strain on a relationship.
6. Marry for the wrong reasons - Marrying someone because you have strong emotions about them (which will eventually go away) or because they are good looking (which won't last) is a great way to eventually ruin a marriage.
7. Never Work on Communication - talking is over-rated. You should just learn to tolerate one another, not really communicate.
8. Be a Workaholic - being rich and successful is the most important thing on earth. Right?
9. Be selfish - expect your spouse to serve your every need and never expect to return the favor.
10. Have Different expectations about money or debt - Spend too much, live beyond your means, and then pay the price. Money is the #1 reason that couples argue.
11. Don't tithe - The money is your own, do what you want with it.
12. Use contraception - kids are a burden that make life miserable. Why take the risk? Of course couples that use NFP are happier, have better sex-lives, and stay married more than 95% of the time.
13. Talk negatively about your spouse - who needs to be built up anyway?
14. Make big purchases without talking about it first - want that new car? Go get it!
15. Spend more time with your friends than your spouse - they are probably more fun anyway.

This list is not exhaustive. You could be inventive and come up with another way to mess up a marriage. If you have one, let me know. We did this previously and got some additional ideas I posted here.
