about commitment, you should at least know how to spell the word.  I was married for 23 years and marred for life.  
Sometimes it works and sometimes it just doesn't.  I don't throw down on people either way.
All in all, you play the cards you have unless you just can't take anymore.  If that happens, game over--period.
Best wishes to the happy couple.  May they live happily and prosper.
