I'm sorry that happened to you, ellie.
It's great to see that you're moving on and realising that this is not the end of the world. The post break up heart ache can really swing things out of perspective. You played by his rules and he didn't like the taste of his own medicine. Personally, I think anyone who will break up with me at the drop of a hat is not worth my time (unless I have somehow genuinely done something horrible like killed their sister or something!).
Good luck with living and loving with your new found freedom. <3
