While a nationwide debate is raging over whether gays can get married, more and more, straight Americans are abandoning marriage, Newsradio 1200 WOAI's Michael Board reports.

  Especially among millennials, living together has replaced marriage, with 30% of 'Millennial' women on a path to remain unmarried by age 40, which is a far larger number than in any other previous generation.

  Steven Castro, a San Antonio millennial, says people his age don't feel in the 'same rush' as their parents.

  "I was saying why?" asked Castro, who has been living with his girlfriend for three years.  "That's why we're moving in, to learn about the other person.  It's the next step in the learning process."

   The survey shows many millennials don't feel they have the financial stability to commit to marriage.  This despite decades of data showing that married people are more secure financially, and can spend more money on luxuries.

  Another factor prompting millennials to say 'I don't' is the fact that women are having children later in life.  It is not unusual today for a woman to have her first child in her early 40s, something that would have been unheard of thirty years ago.

  Social media and social interactions, which are critical to millennials, change when a couple walks down the aisle, according to Castro.

  "My friends who are engaged or who have had relationships for extended periods of time, you don't hear from them," he said.  "It's harder for them to come out."

  In previous generations, marriage was seen as a 'start,' and today, more and more people are seeing it as a goal.
