What's the best way/best thing to do to let myself forget the last hurt relationship?

The relationship was just 5 months and a little be... but I guess because I love him really deep so I still can't believe we are already over. We were gonna see each other by that weekend but I made him mad one of the night. So he canceled the hotel and decided not gonna see me again until he feel better. Now we are still friend text and talk to each other once a while. But I feel horrible because I didn't get to see him one more time before we end up this way.
