That area code thing is REALLY stupid. Where I live, I could go out my front door go across the street, which is another area code, sleep with the hot girl that lives in the house across from mine, come back, and there's a good chance my GF would find out. thusly getting screwed twice in one day. If you're in a relationship, the only person you should be with is the person your dating/married/engaged to. Cheat is cheating no matter how you look at it.
