I can't do this

I can’t lie for you anymore
I can’t stop him from trying
I can’t stop her from hating you
It isn’t my fault you’re crying

What happened between the two of you?
Why can’t you forgive and forget?
I’d hoped this war was over
But it’s hardly started yet
You used to be so friendly
You were mates before I came along
What happened to make you enemies?
Just tell me what went wrong

Please don’t put me in the middle
I don’t want to lose a mate
Why won’t you tell me what happened?
Why did you get back so late?
I’m sorry if it hurts too bad too say
But please just answer me this
When you stopped to say goodnight
Did you give her a goodnight kiss?

I knew it was a stupid idea
Double dating with your best friend
You got jealous and had a fight,
A fight that will never end
You can’t forgive and you won’t forget
Just please leave me alone
I can’t do this anymore
This time you’re on your own
