Lyric discussion by Caruso 

This song to me sounds so much like it's about the singer being secretly involved with a guy who's in a relationship with someone. The singer herself is actually a friend of the guy and the guy's friends, and probably even know the guy's girlfriend/wife, yet they manage to go on without being found out.

"You're going off with her" means that the guy ends up choosing to be with his girl and leaves the singer. And even though the singer is still deeply in love with him, she knows that they "never can be, just because".

"And please call up all your friends And tell them it can't end You don't know what you'd do If you lost her (And lost me, too)"

This means that the singer wants him to admit to his friends and tell them about her, and that secretly she's tired of being a secret in his life. But she also had the hope that he would admit that he couldn't leave her as well.

"I understand the price The cost of craving dark instead of light I flip a coin to see if you still care tonight"

The singer knows what she was getting into, being involved with a guy who already has a girlfriend. She knew it was going to hurt but she took it anyway. And she could only "flip a coin" to know whether or not he actually cares about her, or whether or not he's going to end it soon.

"Baby, tell the world about me The way you won me over In a city you can't remember"

The singer wants him to "tell the world about her", to admit that they are close and how it all had come to happen.

"Oh, baby Oh, it's all right I know she needs you more than I do And I wouldn't win this fight But there is one thing that you've gotta do You've gotta tell the world About a girl you once knew Oh, she wasn't meant to be

But you fell So very deeply In love With me"

This part makes me think that the singer knows the guy's girlfriend personally, like she knows the girlfriend is going through something terrible and needs him but he was with the singer most of the time instead and she's telling him that it's okay if he's leaving her for this girl. She knew he wasn't going to choose her over this girl anyway, but she still wanted him to at least admit about what they have done, maybe because of the guilt. However, it seemed that she was hoping that while confessing to what he has done he would say that he couldn't help but falling in love with the singer even though he knew he shouldn't.
