As long as there is a part of you that you reject then you cannot love fully... When one loves, it overflows, not to a single individual but to all of humanity and all sentient beings... It is a life long process..sometimes, many lifetimes are required..
You strive for the love and acceptance of others. We all do especially as teenagers. You will always be in a relationship trying to make the other person proud. My boyfriend was abused as a child and acts this way. He never heard the words "I love you" and "I'm proud of you" from his fatherly figure.
I suppose what i am trying to say I met someone who blamed everything on his upbringing and refused to believe that he needed to stop blaming others and control his own self going forward but it finished and he will always be a lonely man because of his warped and selfish out look maybe he used it as an excuse for bad behaviour or maybe it was all beyond his control
