theres nothing there that i would think is unexpected, from your perspective. i anticipated he would get flustered by you choosing not to move back. i think he feels he's making progress and that you moving home was a given. it would be natural for him to feel rejected. and scared.
i'd guess that he was expecting you to decide to move home, which may explain why he never came out and said he wanted you to. Going back to what you had said a couple pages ago, you wanted him to voice it, he wanted you to voice it. he was allowing you to make that decision, he didnt want to pressure you, thinking this is what you wanted.
what you felt about needing him to say it, he may have had those same feelings.
continue to show patience, he's going to feel let down. he's going to take it personal. he's walking on eggshells and is scared to say the wrong thing, although he still does, but i think there's fear there.
this is something you'll need to work on, allowing both of you to speak openly (minus the derogatory) and say what you really feel, even if it comes out wrong, without fear of harming each other or the R. patience from you is key here.
there will be some blow back as he works to wrap his mind around the change (the change being in his expectations). he'll probably lash out at you some more, which is what his "questioning the holiday schedule" is all about. he's "punishing" you a bit, or maybe trying to make you question your decision, making you see the difficulties you're causing. again, only what you're causing in the change of his expectations.
him not helping you move is the same, and i think is a good sign. he's saying he doesn't want you to move out, in his own awkward way.
just remind yourself its really nothing personal. be glad he's not kicking and screaming and biting you.
and it may require sacrifice from you to show this is intended to be temporary, maybe in the form of not completely moving out, but taking only what you absolutely need. that may make your day to day life a bit more difficult, but it will comfort him to know you still have your stuff where he lives.
and dont wait for him to ask you to do things. you can ask him too. this relationship is both your responsibilities, to do everything you can to make it work. dont risk it by making unnecessary rules of his turn/my turn, or waiting for him, etc.
if you want to see him, tell him. if you need space, tell him. that's transparency and truthfulness. it would be a shame if you miss an opportunity to spend time together because you were both waiting for the other to initiate plans.
but keep up the great work. i feel my time here is almost done. heheh.
