All it means is your H hasn't shut any doors. While he comments that he belives some possibilities are less likey to happen, he does recognize there's a chance anything can happen ... and by you being optimistic and positive is causing his attention to be drawn to that door back to a happier M ... the one that he is keeping ajar for now. You're doing great! Keep going with what works and in time he will come to think its quite possible to step thru that door.
Quote: I feel like I'm in limbo again
Yes, you are waiting on H to find a direction, so it feels like your in limbo, but your interactions of the last few days are laying the first bricks towards a new, better foundation. You are handling yourself in a different manner than he expected. Its forcing him to look at you in a different light ... a more positive light.
