What is the plan for the week, do you expect him to call?, if he does are you ready with the marvelous plans that you are going to tell him if he asks. It is time to get out there and enjoy yourself, or at least make a great effort pretending to do so, who knows, once you pretend to have a good time, many times it turns into actually having a good time.
You are a strong happy person, always around him, also, next time you see him, look real nice, have your dancing shoes on, ready to go out with a friend.
He is also probably having an affair, but I do not think it is serious, just how he is acting, with the guilt, it is not quite script. Puppy?
