What was I to you?

I've changed towards you. I'm not as nice as I use to be. because I'm tired of being used. I distance myself from you, seems you never want to stay. I pretend I don't care about you anymore. when really it's you all I seem to think about. Even thought I know what's wrong between us. but, I just want to hear from your side. If you never say what you feel? how am I suppose to know what's your feelings? I guess I needed more time to heal. don't keep me satisfied. I should have grown no trust & no hope on you anymore. you never seems to change. you never care. you never understand. you never know. you never remember. what was I to you?
