I'm a cheater...HOW DO I STOP?

Ok, i know everyone is probably gonna jump at me straight away saying, 'once a cheater, always a cheater' etc. But i really don't want to do it. I'm not sure why i do. Please, i don't want everyone to chuck hate-messages at me...i just want to stop. I continue to cheat and i don't think it is cos the relationship isn't right for me. I have owned up to it every time and i have tryed to make myself accountable for my behaviour...telling everyone i know that I AM A CHEATER. I don't want to excuse my behaviour at all but i do wonder if it has to do with not having any real relationship/attention from my dad? Does anyone know any psychology behind cheating? Why do i need realise how much it will hurt before i do something? Tweet
