So taking this back to a couple months ago. Me and a group of friends were going to a concert. I asked everyone if they were all in to see this concert. Everyone agreed. I invited this specific friend, we will call him (jonathan) if he was sure he wanted to go to see this concert since it was not his type of music and since he doesnt listen to Spanish music . I asked him multiple times if he was sure, because i was purchasing the tickets all together and i made sure to tell everyone i needed the money right away. They all agreed and zelled me right away. He was so sure he wanted to go but he was the only one who didnt pay upfront. I let it slide because he was more of a close friend than the others. So the concert comes around and i still didnt see no money from Jonathan. I didnt say anything yet because i was so sure he was still gonna pay me. Keep in mind me and him work at the same place and Im always around him. Ive asked him for my money and he says hes gonna pay me but i still dont see anything. I see him posting on his social media going to games and other concerts when he can pay me back. This is now 7 months after the concert happened. At this point i dont wanna ask anymore because i feel like it will ruin our friendship over some money. He owes me about like $130. Its not much but its more so the principles a person needs to have . If he values our friendship he will at least pay me back and not avoid it every time i asked for it. So AITA for asking for my money again after multiple times or should I just drop it and lose the money and not invite him to any other place ?
