1. My mama told me that the key to a happy marriage is a king size bed. Amen, Mama. Nothing says "happily ever after" like the ability to roll over and sleep as if you are completely ALONE. That being said, separate covers and ear plugs turn mere happy to insanely blissful.
2. Never go to bed angry. Stay up and discuss the issue and move forward. Then, stay up a little longer to plan all the ways you are going to subtly throw this fight in his face for the next 12 months to further demonstrate why you are right and he is wrong.
3. Split the chores. Even if you are a stay home mom (like someone I know), your life will be infinitely better if you split the household duties. Once they are split, reserve the right to change them frequently using the term "but, you're better at it." Then settle in to watch Hoarders as he does whatever chore you are just not in the mood for.
4. Make him feel special. See number three for backhanded compliment that really just gets you out of the yucky stuff.
5. Know that some things just aren't on the table for discussion. Super Bowl Sunday, for example, is non-negotiable. It is not a day to spring "hey, let's scrapbook together" on him. (In my case, it's more of a Project Runway is an inalienable right thing, but whatever floats your man's boat). Just remember, the wedding day was your day... Super Bowl Sunday is theirs.
6. Go into the marriage knowing that your last day of bliss and happiness is probably your wedding day. After that, it's work. It's bills, then kids... then you're too tired to acknowledge each other with anything more than a "I am watching The Bad Girls Club, so if you don't want to, go away." That being said, if you can find someone willing to hang with you while you watch The Bad Girls Club, keep him. That, my friends, is the key to happiness.
Good luck! Godspeed! And remember, if it doesn't work happiness can be only a divorce lawyer away.
