I know I shouldn't and most of the time I am in control of the feelings that make me want to contact her but sometimes I think about the good times and what could happen moving forward if she could understand her part in our failed M. That is when it get a little tough.
Unfortunately, you can't make her understand. She has to come to this on her own, and a lot of the time that takes missing you. She can't miss you if you never go away (so to speak).
That's why you don't contact her.
