I feel like my GF is overreacting and im getting tired of it

Ive been with my girlfriend for 4 years and we've never had any trust issues, ive never given her any reason to think id be unfaithful in any way, but recently a video game I play has been getting on her nerves.

Its a very fast paced and flashy combat based gacha game, which obviously based on genre, includes "gooner bait" characters. These characters will wear low-cut dresses, bodysuits, short skirts, etc(there's also male characters that are just as skimpy/suggestive, but of course, those dont matter because reasons).

She's been asking me almost every time she sees me playing it if I play it for the gameplay or the characters. And just to clarify, I only play it for the gameplay. But this has led to me needing to buy outfits that aren't as revealing to prove to her that I dont play for these character "designs".

I also order drink mixes from GamerSupps, and occasionally I get the free cups because, they're free, why would I turn it down? I've been buying mix for 4 years, and as such, I had collected maybe 10 cups that I just kept in a bin in the closet except the one I used purely as a hydration device. But recently she asked me to throw them all out because she felt like "I wanted them more" or something like that, it was 2 months ago, I dont remember exactly.
