If he wants to be with you, and you with him...that is, to me, saying a lot.
Separating can be useful as a tool I think. Me & H did that, for a lot longer than you, and it gave each of us a new perspective & appreciation for what we had, what was in danger of being lost & that we had to work even harder to save it than we ever thought ~ to get it right.
We had to establish rules for how we communicate. But we didn't really fight, it was worse, no real talking at all!
As to those around you, no one really knows what is between two people, even your therapist. Only you & he know if this can be sorted out.
I wish you only the best in this. I am sorry you are sad...
