Someone on this site, and I can't remember who, so I'll just echo his words, says,
More will be revealed.
Keep on your own path. The more you figure out who you are and what you want, the more clarity you'll bring to the relationship.
It is certainly hopeful to hear what your A is saying. Let him keep going on his own path, and if he really is getting it, you'll see his behavior change in good ways and stabilize there.
In the meantime, follow your own path on your own timetable.
Hugs and support coming your way,
