Need to vent about my gf

So I have started to workout a lot more and go back to the gym which usually makes me pretty tired afterwards. I live with my gf and she of course knows this. I bought a game on the ps5 for us to play because she wants us to spend time doing different things other than going out or staying in watching YouTube which is fine ofc as I’m a gamer.

Today I was really tired after my workout this morning but I just stayed up the rest of the day spending time. As we were playing game I felt my eyes get super heavy and I told her I was going take a nap. She sighed ofc and rolled her eyes and I said be 30 min. She gave me attitude then just let me sleep on her and calmed down. Well 2 hours later I wake up and she says “ can we get back on” I said “ I’m really tired a lot more than I actually expected”

She says “ how over a little 1 1/2 session your that tired” I proceed tell her we can play later tomorrow and she blows up on me and says “ don’t say you going do something and not do it” I just go to the room to distance myself and she sits on the couch on her phone. I ofc fell back sleep after thinking she come talk to me. I wake up and ask her something and she ignores me of course and so I’m back in room just really annoyed how childish she is acting. Am I in the wrong here? I mean over a game?!! I mean if roles reversed I would not be mad at my partner for simply wanting to sleep vs a game.
