There's a lot of variables to this and I love it.
One could be she's being highly insecure and controlling and have trust issues or she's projecting and these are all red flags. Another is you should respect your s/o's feelings. Everyone here is a love and relationship expert, though so it'll be very fun to see what everyone will spew.
Don't like it? Don't watch it. It's that simple
