Ok me (26F) and (34M) have been dating for just over two years. My boyfriend is a professional MMA fighter that you see on TV. He has a small fan base and some include women that are friends with ring girls that hang with the fighters after the fights. Well I was actually with him before he started his contract for fighting on TV. I specified before his fights I do not care about the female fans as long as he doesn't DM them or make plans hang out together. Pretty reasonable stuff. Well fast forward to a few weeks ago he goes out of town and does his fight across the country. He's been liking her thirst traps on insta and she DM'd him to go out to the bar after his fight. Its her and some other MMA people at this bar, he goes. He deletes the messages between them and lies to me about it when i press him. He gets very mad, I get very mad things get very ugly. He lies lies lies and denies until I fess up that I actually saw the messages. Then he comes clean but now I know he is a liar. I'll admit I did log into his insta while he was out of town.. which was not cool. But he eventually apologizes sort of in his own way. Fast forward to the morning after the big fight they are casually texting one another. Conveniently, he never happens to mention he has a girlfriend to her. Bottom line: he saw it bothered me knew it was a line crossed. apologized, kept the conversation going the very next morning after the whole thing. It's about respect and trust. When I confronted him about him messaging her again he said he wasn't flirting and it would be RUDE if he didn't repsond. (wow) Okay. Fine. Two can play that game. There's a guy who I met off TikTok that has been in my DMs who had invited me to Disneyland the day before. All expenses paid. My TikTok is poppin and he is a "fan". I never respond to randoms like that out of respect of him. Since it would be "rude to not respond" and he would not abide to the relationship rules I set; I will be playing by his rules. I accepted the Disney Invitation. And showed my BF. Obviously he is mad but this was his rules? Is this not the same thing? I know the relationship is probably over at this point and many would consider me petty. But he stepped out of line, I am stepping on the line he set. FYI we moved to LA from another city far away and dont have any friends or family to stay with so him moving out would be a whole process. Sadly I still want him more than anyone, but want to prove a point that this type of stuff hurts and is not okay. I also never been to disney and its all expeses paid and would be fun. AITA if I go to Disney with this new guy out of spite?
