Has the Term “Happily Married” Become an Oxymoron?

Just a question for all of you married folks out there!  I wonder sometimes if this statement is still true and whether or not people actually still use it.  I’ve had the pleasure of talking with some married folk and divorced folk and they tell me so many negative things.  They suggest that marriage is an undertaking that shouldn’t be underestimated.  They refer to their marriage as WORK!!!  The complaints range anywhere from “We were happily married for a few years” to “I want to strangle this person every morning when I wake up next to them!” What are their complaints? Believe me I’m no marriage expert but I must say that married folk nowadays with the exception of a few, make a sister want to think twice.
INFIDELITY WHO?
This has to be the number one problem or complaint of people who are married these days.  So much so that I can't help but wonder if there are any couples out there who haven't had to deal with it first hand.  Is this a reality if I want to get married? Whether he or she did the sneaking around, my question is “Was it worth it?”
Nothing better supports this argument than the most recent, ugly, public, exhibition of Swiss Beat’s marriage debacle and new planned pregnancy with Alicia Keys. Egypt (her new baby boy) has an excellent model of the way a man should love his wife. I must say that I have lost so much respect for the image Alicia Keys has portrayed.  She is what many experienced women call a bona fide home wrecker. 
IRRECONCILABLE DIFFERENCES
Honestly, this is just a more pleasant way of saying they fight all the time.  They are constantly mad at each other and their not even sure why.  They don’t get along and really they are not trying to and the worst part is that everyone knows it. These irreconcilable differences are based on a variety of things, a perfect example being friends from the past…women/men who pop up and don’t respect that this person is now married and the married person doesn’t have the guts to put that person in their place.  Why do married folk sacrifice their relationship for a person from the past is beyond me but there are some who do it every day.  I’m not saying that you shouldn’t have friends of the opposite sex when you are married but I am saying that if your spouse has a problem with it, shouldn’t it be your business to come to some sort of compromise? 
THE MILLION DOLLAR QUESTION/S
Are there people out there who still want to get married, and if so why?  Is your idea of marriage based on what you saw between your parents or is it just something you feel that you want in your life?   Don’t get me wrong, I do know some people that are ‘happily married’.  However, I know far more who are not.  A friend of mine said that people get married for all the wrong reasons.  If this is so, I sure would like to know what those reasons are so that I can check my thinking! 

I do want to get married one day.  I do believe that there are people who are ‘happily married’.  My question is why does it seem that the 'happily married' are fewer and fewer day by day?  Why am I constantly hearing from women in conversation that men are afraid of marriage?  If men can be baby daddies, why can’t they be fathers and husbands too? 
I JUST DON’T KNOW
I can’t act like I have all the answers to why marriages seem so glum, all I can do is expose my experiences.  I want someone to make sense of all this, didn’t someone, anyone, get married for the right reasons?
