“Someone has to complete me in order for me to be whole.”
My relationship advice is that the only person that can make you feel whole is yourself.
Realize that the other person has their own life experiences that they need to learn in order to grow.
When you accept that person as a human being and not Ryan Gosling in The Notebook, the quality of life is going to change. Something inside you opens up empowering you that you are fine the way you are.
You are not missing anything and soon the emptiness you feel in your life begins to fade.
