This is not going to be a long letter.  This is going to be the kind of letter that goes direct to the point only because there’s no other way to go but there.  This is the kind of letter I won’t bother elaborating because I do not like you enough to make you feel comforted.

Then again you don’t know who you are.  And I know his secret.  And I’m going to say it.  Not to break your heart or anything like that, but mostly just to say it.  Because I need to say it.  Because it’s the truth.

So here it goes.

He’s cheating on you.  It’s not the first time he did.  And you’re not the first girl he’s cheated on.
