If she is truly watching as much as you say she is, she is likely depressed. Is she nursing hangovers? Is she overweight? Maybe check in and see if she is okay, but otherwise it might be better to just leave her to her hobbies and find someone with interests that are more similar to yours. You're not going to change her, and you've only been dating for a few months. You do not owe her anything.
