Rule one: Don't be looking up pictures of your ex when you have a fiancee.

Rule two: Don't tell this one, anything about that one. That includes showing them pictures.

Applications of these two rules could have saved you a lot of grief. More grief than you know, because not only do you have to deal with her looking for a new dress, but she's wondering why you were looking at her myspace in the first place. You're going to pay for that too. Maybe not now, but wait until you have an argument.
