If I want people in my life am I always going to have to expect or accept a mix of kindness and abuse in?

their behaviours? Because, I am 21 and this thus far has been my life experience. I don't have one single memory whereby a person was just 'good' to me. It always seems tainted with some sort of bullshit on their part. They always invariably end up hurting me or being cruel. My family, the friends I have, work colleagues, aquaintances, teachers. This seems to be the expectation and I don't understand because I am ALWAYS gentle and nice and make sure I do not hurt people. I am really starting to resent this world and the people in it.
