Musty

 You 

It must be hard

 Not to be able to admit that you are a gay man 

What ever you did

 Don't hide the fact that you are a gay man 

Don't come thru

 The vent 

You poisoned me again

 Bitch 

After you smiled in my

 Face bitch 

Because

 You are gay

That's why the

 Marriage didn't last 

You don't want a women

 You want a man 

And that bitch

 Is a dyke

Nigga

 You gay
