What do I mean?

The reason why all my relationships have failed is because I always mean something to someone that I am not I look at someone as a brother they look at me as $50 when they need it and a means to get ahead in life. I look at someone as a lover they looked at me as a way to get out of their shitty living condition. I looked at someone as a friend and in reality I was their maid... What am I? Who am I? Do I mean anything to anyone?
