Wow, idk. Hmmmmmmmmm I guess the problem is that you do not know where it is going. Is this guy gradually waking up and reconnecting? Or is he perfectly happy with this state of affairs. And in that case can you be?

One of the things I miss hugely about my xh is our friendship. The long shared life is a lot to jettison. In my case I never had the choice - he was out of the door and has shown no desire to spend time with me since. In your case? To be honest I would probably go along with what is going on, as long as you are not devaluing yourself. BUT I am not sure that it is good advice.

If you were younger the advice might be different, but as we get older the value of our long term relationships arguably increases.

Would I want to have to make your choice? no I wouldn't. Even not making a decision is a decision.

If you were financially independent would that make a difference to your choices?
