Partner split up with me during shutdown - should I hope for reconciliation

Hey folks, 

I need help. I'm heart broken and I'm trying not to hope because it hurts. 

I'm recently diagnosed on the spectrum (ADHD - hyperactive) and my (now ex) boyfriend presented very clearly as AuDHD. We had a lovely, if slightly chaotic relationship. I love him deeply. 

He's been under acres of stress recently and he was having what I now know as meltdown / shutdowns every few weeks as a result. 

He then started to withdraw fast, then split up with me because he felt he couldn't be a good boyfriend because of it, then went silent. 

I've given him space. I have not texted regularly. I haven't called or gone to his house. I respect his space. 

But - I decided to tell him that I didn't want to split up. That I wanted to support him. That I felt what we had was amazing and I loved him and now I'm scared that this would have absolutely tipped him over the edge if he's having a total burnout. 

I just don't know what to do other than wait and I feel so bad for him. I don't want to hurt him more. 

Please help me.
