As it turns out, any relationship can grow old, stale, or contentious if you let it. I'm only six years into marriage and I still have so much to learn, but one thing Nathan and I found out quickly is that investing in our relationship always pays off in dividends. I know this looks different depending on what season of life you're in (dating, engagement, marriage, children, empty nesters, etc.) but I think it's a universal truth that the most important thing you can invest is time.
Believe it or not, Nathan and I fight from time to time ;) On most occasions we (thankfully) fight about little things that are simply a reflection of our frustration with another area in our lives, a result of being tired after a long day, or just the fact that we are human beings and things will always come up no matter what. Nathan has always been good at checking in on our marriage - how we're doing, how we feel towards each other, how life is outside of our home - and making sure we are on a good track.
Most of the time we are, but there have been times when we've sat down to look and realized our fighting and frustration is much higher than normal...
