Instead of hating him you can just ignore him! If you hate on people it will just cause more problems in many ways. If you ignore him he won't go in your way, It may be hard to ignore but if you keep trying i'm sure it will work (Try to do fun things to make him get off your mind)
Every time you see him think of all the bad things he did to you. If you think about him pinch yourself and list the things he said to break your heart. Every time you see him glare at him. Eventually you'll hate him, so much to where to where.. You won't know what to do! XD
You hate him, the only onje affected will be you. You wont gain anything by hating him. You will only bring curse upon yourself. But if you forgove him, and follow the three step treatment for heart breaks, you will manage to become stronger, wiser, and will acheive more good things for you, and the people around you. Gby.
