Why do some men/women still sneak around?

Anonymous
If your girlfriend/boyfriend is good to you, he/she does everything he/she can for you and you have a pretty good relationship with her/him then why do some men/women still sneak around and talk to other women/men, lie about stupid things etc..if you know you have it good, why would you risk losing it all for something so stupid? I hear people want variety and whatever else, and I can see if your a teenager or in early twenties or so that your not ready to settle down, but as you get older do you not realize that your not getting any younger, and that if you screw around with any good relationship that it's only going to leave you lonely? Why mess up a good frickin' thing?
