Bingo. Some people get caught up so much in their emotions that they can't see the imperfections and failings of their partner. It's one thing to acknowledge an imperfection, make a judgment on it, and decide it's not an issue, but completely another when the imperfection is
an issue but is ignored due to an emotional high. As with Ann's example, you really need to have family and friends interact with the person you're interested in so, at the very least, you will be able to get a more objective read on that person.
Of course, one's friends and family members may not always be objective, especially those who think you can never do any good in your life or ever attract positive persons. My advice is just to ditch those friends and relations because you don't need such negative Nancys in your life.
