Red Flags

I know better than I let on
Somehow surprised when you do me wrong
Get so hurt and decide to write a song
Never know why I'm this way
I'm not great with boundaries
I still let you come and go as you please
Not like you ever took care of me
And yet I choose to stay
But every time I see it coming
And I still hope for the best
Laugh it off like something funny
Then blame it on myself
I looked past the things you said
And how much you messed with my head
Still I thought you were a friend
Despite that the flags and signs were clearly red
Built walls around my mind
But you still get inside
I listen and I know you lie
But I still hear you out every single time
When my friends tried to tell me 'bout your verbal violence
I had my doubts but I tried to hide 'em
So quick to give into all of your lying
Is it my fault if they sounded like sirens?
So much trouble you made
I don't know why I stayed
Not that I didn't see the signs
I just hoped they weren't there
Was selectively blind
I tried not to care
'Bout the things that you would do
And your ugly attitude
I guess what my friends said is true
That all the red flags - they point back to you
