Whenever someone says they're in love after just meeting their boyfriend or girlfriend, I know they're doomed. Love requires awe, admiration and respect, and you can't have awe, admiration and respect unless you actually know the other person. Otherwise, all you have is fantasy. 

The problem with fantasies is that once they become real, you end up feeling angry, betrayed, resentful, and let down. Why? Because you never took the time to find out who the other person really was - you just wanted them to be the embodiment of your fantasy. That is one of the reasons why there is so much rage involved in a lot of divorces - it's hard to stomach your fantasy being taken away by reality. Therefore, if you're a mature person, you have to realize that true love doesn't come from less than a year of dating someone. Instead, you have to think of your relationship as something unique and special that you're going to check out to make sure it's a reasonable match.
