And if your husband won't apologise, you should. While you were misled by him into thinking your dog had been invited, the two of you attended as a social unit so as far as the host is concerned, you were each equally rude by bringing the uninvited dog. TBH, I think one of you should have apologised and taken her straight home as soon as you realised she wasn't supposed to be there.
I did apologize; I just didn't include that in my long narrative. I apologized to our host, who greeted us, when I realized he had not invited the dog. My husband had already left me (gr-r-r-r
). I felt it would be rude to leave then because our host was playing with the dog, saying she was very cute and welcome to stay.
I apologized to our hostess also: Once when I greeted her and realized that she did not invite the dog either and again when we were leaving, although by then I was apologizing for the barking dog, leaving abruptly (& not staying to meet the person she wanted me to meet), and bringing the dog in the first place. I told our hostess that the dog would have been happier at home with her cat, Buddy, and would be staying there in the future. We discussed meeting soon for dinner, which will be my treat.
I planned all along to keep the dog outside because the white carpet made me nervous. The party is held in the back yard, inside, and on the front patio. When we arrived, after the host played with the dog, I took her into the back yard for awhile. I thought DH would at least take responsibility for the dog he wanted to bring long enough for me to put food on my plate, but I misjudged. I thought he would take responsibility for this fiasco, but he is blaming the dog.
"Encouraging" my husband to apologize is guaranteed to backfire. Trust me. After 24 years, I know this about him. I have yet to hear a sincere apology from him for anything, nor have I heard him take responsibility for the unpleasant consequences of his actions. His opinion, which I do not share, is that he is only responsible for intentional
consequences, not stuff that happened because of his actions, but which he did not plan.
