The best thing you could do is find a way to move out even if that means moving in with a friend or your parents and to make yourself unavailable to him. This will help him clarify his feelings and what he really wants. When you’re always around, he can’t miss you and take you being there for granted. If you leave, he’ll suddenly realize how much he misses you and wants you back.
If he doesn’t, he was never going to anyway and at least you’ll stop wasting your time. Should that happen he can buy you out ofthe house, or you two can sell it. As bad as that may sound, delaying your life is not the answer — it’s a waste of precious time.
