He did send me a text from work today saying just to let you know I am at work or did you already drive by to check....
He's upset that you felt the need to check up on him. He doesn't understand your need to know as being a way of rebuilding trust between the two of you. It has to be explained to him in clear terms so that he totally 'gets it', kwim?
How can you work on that? How can you help him to understand?
Getting over a painful experience is much like crossing monkey bars. You have to let go at some point in order to move forward. ~ Joseph Campbell
