There have times in my marriage where hubby and I greeted each other after a long day and could barely make it through the door before tearing each others clothes off. There have been times we've met each other with cold glares and a 'gee, it's about dang time' expression. Times we've spoken or touched only as a force of habit and nothing more. Times we've avoided speaking or touching. Times we spoke and touched in anger. And though we've been married for ten years, the order of these times is not at all in the order you would expect.
We are extremely passionate people. When we love, we love passionately. When we are angry, we are angry with a passion. It wears you down over time, until you have nothing left. When we stopped fighting, stopped trying to 'fix' everything, that's when I knew we were in trouble.
Marriage is so much work, and though this is cliche, it really can be worth it. I never knew I could be this happy and I never knew I could endure so much pain. If you are not ready to do the hard work to get through to the great stuff, do not get married. It is not a fairy tale. He is not your knight in shining armor. He is sometimes a jerk. So are you. He will mess up a hundred times. So will you.
Your most vicious, most hurtful fights will go in circles, dragging you both through the pain over and over until you give up, become comfortable in the fights, quit trying, or learn that this talking thing we humans do to communicate is really, fundamentally flawed because we all speak a different language. And it takes years and years to become fluent in a language, especially when you are foolish enough (like I was) to believe you already speak the language.
It took us seven years, filled with so many happy times, and so much pure hell, but stubborn as we both are, something happened, something finally broke, and my language started becoming clearer to him and his to me and it was amazing. We'd both been screaming the same thing at each other for years, we just didn't know it.
Now, our normal greeting is he'll walk through the door and wrap his arms around me, kiss me softly and smile. Before we can get much more than a 'hello' out, our son and daughter are wrapped around his legs and our house erupts in this joyous energy, all because he walked through the door. My heart still skips a beat when I hear him pull in the drive. And though we've been married for a decade, many people mistake us for newlyweds. Our passion and physical intimacy is much more satisfying and wild and fun and romantic and meaningful than it was in the beginning. And we still have a very active love life, more so than after a few years of marriage.
Basically, we learned to communicate, we learned not to take each other for granted, and we learned it all the hard way because we're stubborn. But, most importantly, we learned it together.
If your biggest worry is that things will be too boring or too routine, then I have to say you need a bigger reality check of what this marriage thing is (especially a marriage between two hotheads). Boring has never been our problem but each couple is different. The one thing I can say for us, no matter what, through fun and fury, through sadness and joy, we kept it interesting.
