he doesn't know what he wants...or rather knows that he is happier and getting along better with you and enjoying the time you do spend together more now and is AFRAID that IF he were to come back that things would just go back to the way they were (classic was...doesn't trust the changes are for real) I'd say just continue on the path you've been walking...continue to make the most of the time you are able to spend with eachother...let him see what he is missing.
