Since you asked...

*If you're going to cheat on your girlfriend, maybe don't cheat with the woman who lives across the hall, and is therefore bound to run into your girlfriend.

**While we're on the subject - if you're not ready to be exclusive, simply not agreeing to exclusivity should solve the problem.

***If you are ready to be exclusive, don't just assume the other person is, too. Hint: Sex doesn't equal exclusive to everyone.

****If you say you'll call - call. If you might not be able (or want) to call - don't say you will. Yes, it really is that simple.

*****Don't assume that because I'm a woman, I'm in a hurry to assign you a label. You know what they say about people who assume.

******I don't care how jaded or cynical you are. If you like someone, and thought maybe you were "more than friends," hearing them refer to you as a "friend" stings, just a little.
