Endure,
Give him the space he needs and if/when he does contact you (and my guess is that he will once you've stopped trying) tell him you want to be there to support him. I told mine the same (except we didn't really break up), it's kind of a weird situation to be in, but I know he's not interested in moving on and neither am I (been there, done that, still came back to each other). Strange to be in limbo, but this time apart to grow and better both of us I'll sacrifice if it means we can spend our lives together. Just be patient. The more you stay away, the better your chances are of hearing back from him in the future.
P.S. You said "I'm not sure he deserves me" I'm sure deep down inside there's a great guy. It's easy to be angry and hurt, but after I've done research I feel better knowing that this isn't about me and how he feels for me, this is about him and his own demons. There's nothing we can do but stand aside and it's f*cking hard, I know. And we need constant reassurance and that's why I like this website.
Also, I just reread what I wrote to you, and it's like I'm writing this to myself, giving myself a pep talk.
Reach out anytime, I'm all ears.
