My first marriage was a colossal failure. I'm the kind of guy who is usually friends with my exes when we break up, but my ex-wife is the exception to that rule. She is a miserable soul, who spread her unhappiness around like manure. We argued DAILY.
That being said, I have since remarried and I have never been happier (though you don't need to be married to be happy). You have to believe that you won't repeat the same mistakes you might have made the last time. Otheriwise, what's the point if you haven't taken the steps to change the things that didn't work for you last time (the proverbial YOU, not you specifically).
My current wife and I have only ever had two arguments, and the second one was a silly misunderstanding. Not that an occasional disagreement is harmful, but my second marriage and my first are night and day different. I wasn't nervous, really. We were in Vegas, so I actually think we were kind of buzzed (well, yeah, we were).
This is her second marriage, too, so I guess it took us both once to figure out what we wanted from a partner ( or more accurately, what we DON'T want) and things have gone very smoothly, even during the hard times.
