The worst betrayal

Just when I felt like I was my lowest
You dragged me back down again
You betrayed me in the worst way imaginable
And I used to call you a friend

A friend should be there when you need them
Picking you back up to your feet
making you feel like you're loved
Making those bad days unique

But the bad times are the ones when true colours 
Show for all in your life
I don't need a friend who will kick me back down
But support me through trouble and strife

I won't stoop to your level and betray you
The way that you betrayed me
I'll keep your dirty secrets like friends should
But the real you I now see

You used me to cover your cheating
As an alibi for your lies
When I needed you you were nowhere
A betrayal that came by surprise

I don't need you in my life like you need me
I have real friends honest and true
And when I have little to give out
I'll save it for them and not you
