So tonight my friends and I were having a big smash tourney/party, good 25 people showed up, including my ex girlfriend. Obviously in order to have that amount of people there, it takes a considerable amount of planning. One of my friends, let’s call him John, tells me that my ex is coming on Tuesday and he has no clue who invited her. He was saying that just to let me know and I figure, whatever, I’m not gonna let it ruin my night. 

Fast forward to tonight. My ex tried hitting on me while I was drawing the bracket and took away my pen because she wanted info on John and a girl who I had hooked up with in the past, who is now friends with benefits with him. Mind you my ex was very insecure about said girl throughout our relationship, but she had nothing to worry since at that point i wouldn’t touch the girl in question with a 10 foot pole. I told her to give the pen back and she’s refusing so I just go and get another pen which she takes as well, so I just say fuck it and let her take them because I don’t want to get involved in her drama. 

I go upstairs to get another pen and continue drawing the bracket, and I see her hitting on a mutual friend of mine who is really into it, and people were speculating they were gonna hook up. I’m fuming. I’m not over this girl in the slightest despite me breaking off an extremely toxic relationship. I play my first round match and I lose because I’m so damn tilted because A, my friend was cheesing bowsers up throw, and B, my ex and the other dude were being really flirty literally 20 feet away from me. 

I just dipped immediateIy tell everyone some family thing came up and just dipped and didn’t look back. I was extremely uncomfortable, but I felt bad dipping on my friends like that. AITA?
