Relationship, FWB, or run?!

Soo we both got out of serious relationships a couple months ago. I'm over my break up and he is over his ex, but he carries mental damage/baggage from the terrible things his ex did to him. It led him into depression which he is going through right now. We have been on a couple dates and have been "a thing" for 3 weeks. One night he spilled why he was going through depression (talking about all the stuff his ex put him through). Then all of a sudden he just said i can't put you through this. That I'm too good of a person to drag down with his depression and past that he doesn't deserve a good person or relationship. I told him to tell me he didn't want me then and he said he couldn't because he does like me but can't do a relationship right now. A few days later I gushed about my bad experiences and how i want to be there for him etc. And that I want to take baby steps. He said he literally can't do a relationship because he has no emotion or feelings right now he is just empty and blank feeling. However, I'm an amazing person and he wants to still hang out and talk. So now we are hanging out alone and doing stuff together pretty much like we were before. Now I'm confused if we are friends with extra benefits, taking it slow that someday could turn into more, or if I'll be stuck in the friend zone. Like what if I stay in his life like this but when he is finally ready for a relationship I'm not an option because I was his friend now I'm in the zone? Is that possible?
