If he responds, and only IF, then you can reply. But even then, don't apologize.
I doubt that you'll hear from him, because he already gave you his answer... wait until after you graduate. When will that be, how much longer? If your feelings are still there for him by then, you can extend a new invitation.
So just let this simmer gently on the back burner until it's time. In the meanwhile, if you see him, smile, say hello... that's all. :)
