I'm going to make my girlfriend watch a 30 minute show about whales even thought she hates documentaries.
Why do you want to make your girlfriend watch a 30 minute show about whales?
She always makes me watch reality shows with her so I want to make her watch an educational show.
I know you're unhappy watching shows your girlfriend wants to watch, but you should find a way to compromise and find shows to watch that you both like. You shouldn't force someone to watch shows that they don't enjoy and I'm sure you can find a compromise.
Nah, she can watch it. Let her suffer.
Forcing your gf to watch tv shows against her will is controlling and mean and doesn't allow for compromise. Work with your gf to make a schedule for the tv shows you both like so that you can both be happy.
