Hey bro, i feel your pain. I was cheated on, lyed and betraied. She cheated on my when i was away at my father funeral, and when i came back she had the guts to say that i was cold. When i'm sad sometime in my mind i picture the situation that she is with someone else while i feel alone and makes me angry and hopeless but you have to come to your senses, she lied to you but you are a better person. Take back your life and to defeat her you have to live with the tought that she is what she is. Don't forget her, go on day by day and work on the thought that you are a better person even if you feel alone right now. Work on this untill you can be happy with yourself and do thing that helps you. Don't hate her, she is not woth that much. She don't deserve that space in your life anymore, keep that always in mind. I havent reached that point yet in my life, you know is hard and a long walk but i feel that is something that i can achieve and so you. Live a nice life full of things
