Well, I'd guess that there might be an amount of time that he's actually physically residing at another location when that location would be legally considered his primary residence. Not sure if that would matter in the courts. In his mind... we'll, he'll think what ever he wants.
Keep doing what you are doing. NP with sending him HFD wishes or texting notification of the blackout. So long as it was strictly informative and had no expectations attached.
Pursuit is unlikely to work, based on your description of his behaviours. Unless he wants to engage you in comm, he won't.
Also, even considering the context of your open M, most M recoveries do not begin while there is an OP. Considering you believe that he is currently in a mono R with GF, that rule of thumb probably holds in your sitch.
Keep doing what you are doing. Continue to GAL and 180 where you can on what's valid and keep working on your own personal growth as you can.
