It's my school's prom tomorrow, but?

I'm really really scared. I'm going with my boyfriend, and I know he will keep me company through the night. However we don't get to choose who we sit with for dinner. The teachers have put me and my boyfriend with a few girls I don't get on with. They really don't like me. My boyfriend doesn't like them either but he's a really sociable guy who has the ability to get on with anyone, whereas, I don't have that ability. They like my boyfriend (not in that way) so I'm just going to look like an outcast. I don't want to act false and pretend I like them just because it's prom night. I'm scared of what to do? :/
