That hadn't happened before, even during the engagement.
When we got married we thought it was going to be all bliss and happiness for life. By about week two we both had an awakening.
Something about being exact opposites and together 24/7.
We clashed about something so important I can’t even remember what it was. We hadn’t really ever had that happen while engaged.
Suddenly we realized that the bliss and excitement was growing into, well, everyday life.
And all that passionate romance that had driven our relationship was growing, well, less passionate.
We both realized our marriage had entered a new phase, one of many, through the years.
And we needed to be much more purposeful about making sure it worked. Purposeful because the blinding emotional love some days seemed to be asleep.
Yet, we both had committed to our marriage. For better or worse. So we decided we had the potential for either. We needed to make it better or it would become worse.
We learned to really talk. Even when it was difficult.
We learned to argue without hurting each other.
We purposefully expressed love even in those times we didn’t especially feel it.
We built romance into our relationship even when we didn’t feel romantic.
And through the years our relationship has grown. Sometimes through difficult times.
Heck, sometimes through difficult eras.
Yet, we both never gave up the dream of making our marriage great. We never gave up the ideal of living together in love for a lifetime.
And because of that, through all the trials and triumphs. Through all the frustration and bliss. Through all the sameness and romance.
We still everyday enjoy our love and each other. And can’t imagine life without the other.
Well actually, there have been probably a couple of those days for my wife. She’s just too nice to say it.
A great marriage isn’t built because it’s perfect. Only because you keep trying to make it perfect.
