about a week ago i (23m) recently had my 5 year anniversary with my gf (26f). to celebrate we just had a dinner for the two of us. it's an informal thing ofc, but we dressed up and stuff. it started out good, and my girlfriend wanted to invite over our friends. that was fine with me, esp because they were just nearby, and after an hour they came by, but once her friends joined us, her tone shifted

my girlfriend started making these like weird jokes about me to them. please note that i'm not really super close to these friends of her, but she said stuff about how “i can't believe we made it five years, i thought we would be done by the first". she also said how “i guess when you hit your late 20s, you stop being picky.” she's never made these type of jokes before, but all of sudden she just makes them now? her friends laughed, but it was just like awkward laughter, so its not like they were even enjoying it that much. i sorta just smiled along to match everyone, but everytime she said another joke, it just kept hurting me a little more and more.

but then, my girlfriend made a joke about our daughter (1f). she said "me settling for (me) led to our baby, so ig i played all of my cards right." that was it for me, and i told everyone i wasnt feeling great, and i left the restaurant. i just walked around the area, but i just needed to get away. she texted me later saying i “ruined the night” and made her look bad in front of her friends. i said sorry, but i told her she was being weird. she said she was just teasing me a bit and that she was sorry. i decided to go back to her and apologize to her friends before driving us back home. in the car we continued to argue, and it was just us going back and forth about how i was being sensitive, she was being weird, etc.

a week has passed and it's somewhat behind us now, we're just so busy with other stuff we cant really care about this anymore. but, i still do. i don't understand why she'd make that type of joke on our anniversary of all days. like i said earlier, she never even makes these jokes, so why'd she feel the need to say it then? but, at the same time, i did kinda ruin our dinner. i made her pay for everything, like i just messed it up. so AITAH?
