dear hades,
i'm sorry that i cannot answer your question b/c i don't know his reasons. i know that it's hard, but if you can try to use this time to focus on yourself.
and also, someone told me once long time ago, that not many things are final. you never know what the future holds. i mean, i'm not trying to give you false hopes or to encourage you to waste your life waiting on him, but people do change their minds all the time.
take care of yourself. you cannot change who he is or what he decides to do, but you can help yourself. you can be the best that you can with or without him.
my hugs and prayers go out to you tonight. hope you feel better, b/c things will get better. every problem has a limited life span, another thing that i was told. unfortunately, some seem to live for a long time.
take care and welcome.
