Love is pain

How can u love someone so much then watch them walk away... It hurts to bad! But you got to know when to let the other person go no matter how hard it maybe! Some relationships are harder to keep together... Some have lots of tears and blood... But u will always have that one person in your life . You may not even know the person or maybe you do! Maybe it's the person sitting next to you... Or anyone close.... Me I have no one.... I got dumped recently then found out he ran away. He started cutting because of me and I started cutting because he was hurting himself and he didn't deserve it! I love him to pieces and ill never forget him... But I had to let go of him... He was making me so very ill and I almost commited suicide a few days ago... He hurt me so bad.... It's funny how the people you love hurt you the most... I never understood that till I started dating... Now I get it. I'm sorry if this seems random... But I just felt I should tell who ever is reading this you r loved by me
