Don’t catch feelings! Don’t fall in to the trap. That guy showed you his character. Believe it. Because trust me when I say even if he does decided to come back you’re gonna possibly be left worse off one way or another. His comfort in the way he handled/ended things & stopped messaging you are red flags. Letting it go & keeping it pushing its the best way to save yourself. But I know in life people make their own choices. Live & learn. You do what you feel best. And from a probability stance I could always be wrong but just keep your guard up & don’t cut yourself off from other experiences because of someone who may not do the same for you. Live your life to its fullest.
