Did you ask him can you just carry the stuff up for me, then you can come back down? Especially when playing a game they kind of get sucked into it. Thank god my husband isn't into that stuff anymore, but he used to be quite a bit, and it would consume him! I don't blame you for being mad, I wouldn't be nice about it after a few times asking, my husband wouldn't make me stay up and wait for him either, he'd rather just get me out of his face and do it the first time, haha!
Sometimes guys are a little clueless and we have to spell it out for them over and over.
