If you have truly found the one that you want to grow old with; marriage can be a truly beautiful thing. Yes, it has it's tears: both of joy, and sorrow; but the journey is definitely worth it.
This is coming from someone going through a divorce, so what do I know; but I know that it can be a wonderful experience--this is me optimistic that God will send the "right one" my way.
Blessings,
Jon
