I don't know about this one. You will never know how much the way you treat him affects the way he treats you until you try something different. I think at the beginning that is really hard. But when you have both detached and moved on and a lot of the hurt has dissipated, it gets easier and easier. I know that since I have made fewer assumptions and have expected things to go more positively they have. I personally enjoy not feeling paranoid all the time about what he is up to and just accept things more at face value.
