How do I tell you?

How do I tell you how much you matter to me when I'm afraid to commit to you.
You have always been there for me but I'm rarely there for you.
How is it that you can still love me for all my faults?
We are walking down different paths in life and yours looks so much better than mine. I've tried to cut across to you but only get caught in the thorns. Even then, you're there to save me and I don't deserve it.
Again and again I've caused you so much pain, why do you not leave me to wither and die?
You say that you love me but how? how can you love something that is so broken and weak?
I say all these things, but at the end, I need you, I need you more than you know.
Thank you for all that you've given up to be there for me.
I can't say this to you or out loud but I do love you. I love you so much.
