When embarking on the journey to wedded bliss, it's natural to feel nervous along the way. It's a big change, particularly if you're not used to living with your soon-to-be spouse or sharing finances, having kids, and all the other trappings of marriage. The runaway bride has become a cliche, but if you really feel like running as far as you can get in those wedding heels, then it may behoove you to listen to those feelings. A new study recently published in Science magazine compared newlywed couples' pre-wedding feelings with how they felt six months after getting married. Those pre-wedding gut feelings – whether acknowledged or not at the time – seemed to carry over into the marriage, according to Florida State University researchers. They had 135 heterosexual couples fill out questionnaires individually about their feelings about their new spouses to assess what they call "conscious responses." When given time to consider their feelings while possessing the knowledge that their answers would be seen by someone else, individuals were generally optimistic.
