AIYTAH for saying there was no joy in a company pool tournament?

My (27M) work has pool tournaments at certain times of the year during lunch break as a team building thing, it’s pretty chill, nobody takes it too seriously except my friend G(26F) is fiercely competitive. She was getting stressed about the tournament but won their first few rounds then it ended up she would be playing me and she freaked out.

From the minute she found out, she began telling everyone it would be her most stressful game and anytime she was practicing at lunchtime she would be trash talking me if I was in the room and not even playing, to the point a manager asked me what was going on and why was she so mad at me. In our last tournament she pulled out because I was her opponent, and we had to convince her to not do it again this time as it could actually look bad for me in the company if it kept happening and managers would obviously start asking questions.

This isn’t a situation where we have issues with each other, we are genuinely very good friends and spend a fair amount of time with each other outside of work, more than our other co-workers, we even have a short holiday booked together in a couple of months, so when I tried talking to her about this, she said she just was getting stressed about the match and just that she “has stronger emotional reaction towards me”

In the lead up to this game she started talking to me less, if we were working on something together and I helped her, she didn’t even say thanks, she would just put her earbuds in and go back to work, give one word answers when I tried to talk to her, and generally just be really hostile. We also had a difficult conversation about the upcoming holiday that she wasn’t happy about which also added to the tension, but she kept insisting things were fine.

Needless to say when it came time to play,I was very over it. I just wanted the match to be done, because I honestly didn’t care much about it. She spent the morning leading up to it telling everyone how she didn’t want to play. During the first game I didn’t say a word the whole match because I didn’t want a reaction from her, but then between matches, a manager noticing the tension passed a comment like “I hope you two remember to have fun”, and she began telling them how I know if I beat her at the match, she would just stop talking to me for a few weeks until she stopped being mad at me.

Where I might be the asshole is, when she said this, I just said “there’s no joy in this match, Ive had to deal with so much leading up to it, and I’ll need to keep dealing with it if I win or lose, I just don’t care anymore” when I said this, G started tearing up and said ‘you know I’m just joking around right?’ and I said ‘No, it’s been weeks of this already ‘ and she burst into tears resulting in all the managers leaving the room.

We both ended up getting pulled aside later and asked what was going on, but they knew how intense she had been about the match so thankfully nobody got in trouble. We had a chat that night and things are mostly ok between us, turns out she was not entirely fine about the holiday discussion, but now some friends have been keeping their distance from us, some of our usual work friend group were keeping their distance at the holiday party and generally have been very weird to us.

Tldr, my friend got stressed about a holiday tournament at work, was taking it out on me, and I told the room I didn’t think there was any fun to be had in the match
