I don't have any wise insights but wanted to say maybe it's possible you could just see him/talk a bit less rather than not at all? It does sound like quite an intense friendship (some of us have a tendency to those!) and maybe a bit of space would give you a chance to sort your own thoughts out.

Only other thing I would like to add is that you mention feeling like you want him to be more emotionally supportive. From my experience even those of us in established relationships can sometimes expect more from our partners than they are able to give. It can be a difficult feeling to sit with, but in any relationship (Friend or romantic partner) sometimes we are alone - if that makes sense.
