I don't know you.

Why am I still so wrapped up in you?
It has to stop.  You don't define my worth as a person.
I define me.  I was fine before you showed up and I'll be fine when you, inevitably, leave the picture.
You play mind games.
You won't let me know you.
You do things like we're still together.
Rationally, I know we're not.
Every time we're apart I realize all these things.
When we're together I forget it all again.
I let you make me blind.
So keep pretending I don't know you.  I know more than you think.
