The truth is that it may not happen... All you really can do is hope! If you really love him and it is meant to be it will be. This is the way that life works. You need to move on with your life and maybe try to find someone else and then if sometime in the future that is what's suppose to happen. It will. Trust in god and he will guide you to your path. everything happens for a reason sometimes its just not meant to be. I hope it works out the best for you!
