no worries, anon. the problem is that you didn't establish these rules the first time you met your roomie. now he's going to think that you're being confrontational and establish yourself as the alpha male who orders around the house. remember that even though we're humans, we're also animals. extremely territorial animals if that. since you didn't establish boundaries, he unconsciously thinks that the whole place is his domain and you making these rules right now means that you want to take over the domain.
