While I agree that it is important to have positive expectations of one another and your marriage, we think putting one another on a pedestal or looking at your marriage through rose-colored glasses could lead to problems.
Sure, every married couple is unique, but generally, issues and problems will arise in a marriage and they won't evaporate magically into thin air even if love is blind. But that's not what some researchers believe.

Dr. Sandra Murray: "I wouldn't argue that people are 'deluding' themselves. Rather, people are seeing their partner through an optimistic [or] idealistic lens. Generally that is beneficial for relationships because seeing a partner in the best possible light gives people greater reason to believe that they can deal with problems within their relationships."

The University at Buffalo study mentioned in the April 2011 edition of Psychological Science, "Tempting Fate or Inviting Happiness?: Unrealistic Idealization Prevents the Decline of Marital Satisfaction", involved 222 couples over a period of 3 years.

Karen Hopkin: "People who had seemingly unrealistic expectations of their spouses were nonetheless happier than more realistic mates in a marriage's early years ... they found that people who maintained the most unrealistic view of their better halves were actually the most satisfied with their marriage. When the honeymoon's over, it could be that those who idealize their mates may be more likely to forgive the transgressions that arise when people are no longer on their best behavior. Whatever the reason, the study suggests that couples should exchange rings -- and rose-colored glasses."

I think the study needed to cover a longer period of time -- at least ten years. Twenty years would be even better. Your thoughts?
