AITA for watching tv after I finished chores?

I live with my partner and we split the chores pretty evenly. I work from home so do more throughout the week such as laundry then at the weekend we have our own chores to do to clean the apartment. My girlfriend stated when we moved in together which chores she would prefer. Whenever someone else does the chore for her she will do it again as she likes it done her way. She also does this when she was living with parents.

The chores I have seem to take less time than my gfs so I'm always finished first. I've asked multiple times if she wants me to do any more on a weekend and offered to do some of hers but she says no and that she's fine with how things are split. Last weekend I had finished my chores and went to the living room and put the tv on. My gf walked through the living room and saw me sat down and just commented "it must be nice".

I asked her what was wrong and she just said she thinks it a but of a joke for me to be sat relaxing while she's sat cleaning. I asked what she expected me to do since she doesn't like anyone doing her chores and mentioned that I have offered repeatedly to do more and she says no.

She didn't answer and just said it's annoyed her that she's cleaning the apartment and I'm just sat relaxing wit the tv on and playing video games etc. AITA for watching tv when I have finished cleaning?
