Do I continue to move on or give him one more chance?

In my opinion, if he really loved you he wouldn't have ever broken your heart in the first place. But, I understand it happens once to a majority of the population. Just give it time, time is the key. During that time period you'll encounter so many other people out there that could be the true one. It's up to you, if you like to give him another chance , shoot , go for it. You will learn from experience. If all doesn't go well, maybe it's time to slowly let go.
