AIO for refusing to deliberate lose when we play games?

This is going to sound petty and I agree that it is. My girlfriend likes to play board games and games together on the Nintendo switch. Some of these game are just luck anyway with no skill needed but some of them you actually need skill or knowledge. We tend to play Mario party, Mario kart, monopoly and just other switch games .

I've been playing games a lot longer than my girlfriend so I am better at a lot of them. This means I win a lot of the time. Not all of the time though and there are still quite a few times my gf wins.

The issue is she's starting to get annoyed whenever I win. I've tried talking to her about playing different games, maybe not playing at all if that's the reaction she has etc but she refuses.

She said it's shit watching me win all the time and that I could always let her win at times. I mention that she's not a child and me letting her win would be obvious so wouldn't really change anything.

I also point out a lot of the games are just luck anyway so I can't really do anything with that. I mentioned that there's no enjoyment in it at all for me to just sit back deliberately losing.

I've bought her new games, we've tried co op games such as it takes two, split fiction and Lego Star Wars but she just gets annoyed whenever I do anything first or if I get more coins in the Lego games etc.

She said I should just want to enjoy playing the game with her and should be fine letting her win but I pointed out the same logic could be applied to her in that she should just be fine playing the game with me and be fine with me winning but she said it wasn't the same.
