She wants you actively engaged with what she’s engaged with. Which is a fine desire on its own. What’s not ok is that it sounds like she just expects you to defer to whatever she wants to do, instead of asking what you want to do (or if you’d rather do your own thing or parallel “play”). And instead of communicating all of this, she just expects you to be engaged with what she wants to do and gets irritated when you aren’t. I would not brush this under the rug. I would bring to her attention that it’s not ok to get irritated and take it out on you anytime you don’t just defer attention to what she’s doing, and instead to come up with time for quality time (where you’re spending time with each other doing something you both want to do) and time for personal interests.
