It is obvious he doesn't want to continue in the relationship (or even reunite). It appears he has even included the relationship as the reason for lack of progress in his life the reason he broke up with you.
You will have to move on. It hurts but with determination you can heal and recover from the breakup. This means no contacting your ex in whatsoever means. It will be a good idea to den your ex a text after two weeks of no contact to thank him for the time you had together and to wish him all the best. This gesture is paramount as it will aid in the healing process.
Block or unfriend him from your social media accounts and whenever you tend to think about him, snap out from those thoughts by telling yourself he is no longer in your world this you've to stop thinking about him.
I have written an article on how to heal and recover from the relationship. You can search this title on any search engine: Steps to Heal and Recover from a Breakup.
Remember, your determination to heal and recover from the breakup is the main factor that will determine your moving on from the breakup.
