I think you should not worry about how he is going to react.
My opinion is to keep the focus off of him and on yourself. You can not control what he does - you can get more popcorn, pull up a chair and keep watching the movie.
Nothing you do or say can shorten his crisis. By not staying detached you can make it longer.
Touch and go's can eventually lead to reconnection, as they get more frequent and longer in duration.
Sorry you are anxious, what can you do to FIX that?
