Yeah that is weird. But then again, one does look for perfecting a relationship and she wants the good of you in someone else, because it didn't work out. Shite I do the same, it's because you loved someone and you see the beauty in their look and it reminds you of happiness. Doesn't really help ya, but yeah it is real common. The worst is when your the guy a girl chooses because your like her ex, and she doesn't see you for what you really are.
