How do you know if you've found 'the one'?
According to Anne Milford, the married author of "How Not To Marry The Wrong Guy" who called off her first wedding five months before the Big Day, it's about that "certain spark."
"With my first fiance, I just felt that there was a certain spark missing," she said recently on HuffPost Live. "Anybody whose been married for a long time knows that you don't always have that fire and flame always burning, but you just always need that little spark, that attraction that you can always go back to."
Milford advised viewers to listen to their gut feelings when it comes to walking down the aisle.
"As you move forward, you establish what you want, what you don't want, what works for both of you," she said. "[Don't] ignore those gut feelings. Don't suppress it; pay attention, listen to those doubts -- when in doubt, don't.
