My girlfriend and I have been dating about two months now, I have met most of her family but today we had dinner at her uncle's place, whom I have not met. Now let me preface this by saying I am rather reserved, quiet, and get drained where lots of chit chat is going on. I know obviously to keep up appearances for others' sake and do my best of course. So her cousin, who is 18 had a girl over and he told everyone he plans to ask her out latet that night. We got there around 4:30pm and started making food a bit after. Now everytime the cousin or the girl were out of the conversation, someone would instantly start asking when he is gonna ask her out, how he is going to do it, where, etc, all sorts of questions that I don't see people needing to know. But it might be their family dynamic so I just took it as that. This went on ALL night and then as soon as the cousin and the girl left to take a drive, everyone started looking out the window and trying to look where they are driving to, even though it's pitch black night outside and can only see the city lights. Then the cousin's sister strarted to track where he is on the Life360 app. Even checking to see when he got out to walk along the beach. All of them were just giving their opinions about the whole young love thing. My girlfriend's uncle was perhaps starting to see everyone was starting to get a bit..too much about this and asked if we wanted to play pool. I said yes sure and started taking the balls out, but the others were not budging, basically people just taking turns asking 'where is he now' over and over. I saw the pool game to just kinda break away a bit and asked my girlfriend politely can we maybe do something else for a bit, to which she asked if I'm getting annoyed, and to which I replied yes kinda. She got instantly mad and just sat down, continuing as if I'm not there. After a bit the uncle asked us again go to play pool as it won't look good if the cousin and the girl is back and everyone else is sitting there, obviously discussing them. We then finally got up and away from the whole thing. Later that night my girlfriend and I got home and told me can we talk please. She then told me she is very unhappy with me for getting annoyed and having the 'audacity' to suggest we go do something else. Saying she would never do that while at my family, and that I ruined the last bit of the night for her and then started crying. She said she doesn't know when she will see them again but they live like an hour down the road, I don't get it. Said she was so excited to have me there but if this is how the relationship is going to be, she doesn't know anymore. Honestly I just feel she reacted way too strongly and didn't try to see it from my perspective. I feel she is out of touch with the whole thing. AITA for telling her I want to kinda go relax for a bit or was I being too selfish?
