Its only been 5 days and that may seem like forever right now but it takes a while for the heart to start to heal. The only advice I would give you is don't accept any communication from him if all he is going to do is give you false hope. His reasons don't matter because at the end of the day the result is the same. Give yourself the time and space to get to a place where you can think clearly about this. Then you can make decisions which are equal part head and heart and not all heart.
