Part of me will always love you. But it's okay, because I let you go a long time ago. I hope you'll have a great life. I know I will.
Not everyone has experienced losing the one that they thought they would be with forever but a lot of us have. It is very true that when you once love someone so much it is pretty much impossible to just let that person go completely from your heart. In order to do so, it is best that you completely cut this person off. Once you have talked to this person and come to a mutual agreement that you shouldn't see each other anymore, make it a point never to "see" this person again.
