I (21F) had my 21st birthday yesterday. My boyfriend (21M) spent the day with my family and me and we went to a restaurant and drinks and my parents payed for everything as organised a lovely day for me. On the night time my friends came over (all girls) and a few brought their boyfriends, who are all really good friends with my boyfriend and have always made an effort to make sure he is included. There was 9 of us at my house and we needed two ubers to get to the restaurant for the night time so we all decided to get an uber xl that fits 6 people and then a normal uber. Me and the girls decided to go in the xl as there’s 6 of us and the boys were going to get in the smaller one. Nobody else had an issue with this except my boyfriend who seemed to kick up a fuss because “a boy should go with the girls” for some reason even though this would mean one of my friends having to be separated from the girls which just doesn’t make sense. When everyone in the room shut down this strange idea, is when his mood changed. He went upstairs and unbeknownst to me was packing up his things as he had stayed the night that day. When the uber arrived he said goodbye to everyone and my parents as if nothing was going on and on the way there told the driver to drop him off at home, leaving the boys in the car confused. I frantically began calling him and he told me to stop ringing him, we had plans to go to liverpool which he then said i was no longer welcome to come on. I was distraught as i had no idea how such a small issue had escalated to this. I spent the rest of the night completely heartbroken trying to enjoy the plans i had been looking forward to for months now. His explanation later being that because none of my friends agreed with his idea about the taxis and i didn’t “stick up for him”. Now he’s frantically calling me crying and apologising but it’s the next day and it’s too late. My parents are so confused, my friends no longer like him anymore and i just don’t know what to do. For the rest of my life this is how i will remember my 21st birthday. We have been together over a year now and never ever has he behaved like this. He has always gotten on with my friends and they have always made the effort to include him and now they feel a bit hurt that he would accuse them of making him feel left out. We were supposed to go to liverpool tomorrow and i don’t know what to do?
