AITA ,so my bf (18) got tickets to a concert , the tickets were cheap (£13) each , I really wanted to see them with him , when we got there , I didn't have id with me ( this was the first concert I've been to , so I didn't know ) so I got stamped underage , he had I'd, so he got the overage stamp , I was really thirsty , so I asked if we can get some water , he said he will get two beers , I said in stamped underage, but he did it anyway, we got caught , and I got told I had to leave, but he could stay , he met out front with me and told me , I said he could go , because , that's what your meant to do, but I looked really sad , it was beyond clear I didn't mean it , but he said he was gonna stay . He left me in the middle of London , Drunk and high , an 18 year girl . Then it turned out , he couldn't go back in , so he came home , and made it feel like I ruined his day . AITA For bringing angry , and IiTA for wanting to tell him
