Wrong or right?

Tonight my bfs friends... Husband and wife came over unexpectedly while I was showering...my bf came in and said not to come out because they were here... When I was done I yelled for him and he came and I said I needed to get clean clothes and I would wear my robe to get to the bedroom which is thick and floor length... He freaked saying it was inappropriate to walk infront of his friends that way and to stay in the bathroom until they leave because it won't be long... I became rather upset and asked him to just go get me clothes to which he became frustrated with.. Eventually he had them go outside to smoke a cig so I could go to our bedroom in my robe and put on clothes.. Call me crazy but I think it's ridiculous he acted that way.. Like possessive..??
