Not sure how we have managed to hang in there for so long. We have little in common and ours is not a romance filled love affair, but on a practical level we work well together and have raised 4 children who turned out really well. Only one of those is his biological daughter, but he accepted and cared for the other girls as if they were his own.
I certainly never imagined we'd make it this far and now I see it's possible that we just might get to the big 50 if we live long enough. Romance fades, but a good solid friendship can carry you on together for a long time, our marriage is proof of that.
