It's all fun and games until it happens to you. Then, you'll know what true pain really is and you'll feel like shit for doing it to other people. Believe me.
And you don't have to physically cheat. You can cheat with your heart. That's not as bad but don't act on it (*edit* what was I trying to say, here? Oh well...) I'd be just as hurt if the person I loved was in love with somebody else over the internet or something. Either way, she's not happy with me.
My advice, if you're not happy and you're not in love anymore, leave that other person alone. Don't waste their time and energy.
