My dearest Belle....you blurted out what you felt...you are afraid of getting hurt again. Maybe not what you even wanted to hear yourself say but there it is...the elephant in the room.
He's a good man and even you said...doing everything right. This is not something he can fix. Only you can. It takes time and maybe a little help from your friends....maybe a visit with your T. You have this 4 weeks (and the next 4) again to work on it some more. Read, talk, think.....
Be gentle with yourself. Expect this to take time. You know I think of you as a friend and there are others who do as well. Get down to the nitty-gritty...roll up your sleeves and attack this like you would if it was a task from your boss. What would you tell me if I came to you and told you "I am still feeling the hurt from my past?"
You care for him....that is a feeling. You know what it was like the last time you felt that for someone....thus the fear. He can't do enough right things to take away the wrong that was done to you.
I care about you...if I can help you know where I am
