How?

How can you love me when i cant even love myself?
how can you be there for me when all i do is push you away?
how can you say you never want to loose me when i hurt you everyday?
how can i be all you want when i refuse to give you all of me?
how can you say that you can't picture me leaving you but all i can see is you leaving cant you see?
you can do so much better than me but you choose to keep me here with you how...?
is it a test to see how much your heart can take before it cracks?
is it a game to see if i will eventually trust you?
how can you do this to yourself?
i love you so much but i just cant figure out how to show you.
how can i do this to you?
how???
