hi kirsty22,
Having letting go of someone you love who wants to be set free is always difficult. True love is about letting go when the one you love no longer wants to be with you. It doesn't mean they don't love you, just he opposite. Loving somone enough to realize you don't want them in your life for the rest of your life as a mate and allowing yourself the courage to tell them that dispite the pain it will cause is really a mature, responsible and loving person. You don't have to like your ex boyfriend decision, however, you do have to accept it. Perhaps, when you get older and he gets older and you have stopped arguing and mature, your relationship may take on a new direction, I wouldn't wait around for that to happen but on never knows what the future holds. For now, please let him be and work on yourself, love you the way you love him and watch what a beautiful person you will become from the inside out.
Good Luck,
Faded Rose
