Love isn't what you expect it to be. You imagine being drunk on happiness, but the truth is, you worry all the time. Is she ill? Hurt? Might she meet someone else? There's a moment when you realize that you've gotten everything you wished for. And right on its heels is the understanding that this means you have so much more to lose.
You've seen those pictures of couples kissing in front of a Christmas tree, or clasping hands on their wedding day, or holding a newborn baby between them—a snapshot of joy. But what do you really know about them? Just that at the second the shutter clicked, they loved each other. You have no idea what trials and tribulations came before, or after. You don't know if one of them cheated, if they grew apart, if a divorce loomed on the horizon. You simply see that in one static moment, they were happy.
