No reciprocation

So my fiancé was supposed to do “something” for me tonight and he made a huge deal out of doing it most of the night. Well one of his friends came over and we’ve all been drinking. It’s been a couple of hours and I’m like hey let’s go to “bed” so he follows me in the room and then proceeds to tell me he would rather drink and play video games instead of doing anything with me tonight. How should I respond to this?
