You don't have to lose hope, but you should be realistic. If he broke up with you because he wanted to date others, something was missing in the relationship (sorry, I know that hurts).
You can always do the no contact, sometimes it is hard for them to miss you if you are still talking everyday

. Just tell him that you still have some deep feelings for him and aren't able to talk to him as "just friends" right now. Perhaps then he will realize how much you mean to him.
Just keep in mind, the break may or may not be permanent. Don't stop your life for him
Good luck to you, and I hope you are able to get back together
