Please don't backslide. I think your encounter when you arrived was so positive. If you talk R now or ask him the wrong questions you'll send him away for longer. Keep acting as if and strive for baby steps. Now is not the time to ask to move home. I know it's hard but you must go back to Poland and continue with what you're doing.
As for the joint session...can you do it by yourself? Maybe change it to a session just for you? I'm sure Jody won't mind.
As for the sex? Most will tell you that sex for a man is NOT just sex as we women have been led to believe. If it were just sex then he'd have "just sex" with someone whom he never shared emotions (good and bad) with.
Hang in there and keep a PMA!
