Sometimes women stray temporarily from their man a bit in order to test the waters outside of the safe harbor of the relationship. When a relationship is so safe that it is boring, many women feel like they are missing out on that sense of excitement that they feel a relationship is supposed to bring. Sometimes, a woman who is otherwise happy in her relationship may flirt with another man or even go out on a "harmless" date with him. One thing leads to another and suddenly she starts to fall for the new man. Not because he is any better - but mainly because he is just someone new and different.
