Input: Text: so my good friend from high school is getting married pretty soon and i was tasked to be the best man. i'm not really the most outgoing/social guy there is so setting up the bachelor party wasn't something i was looking forward to. most of the people that i was supposed to ask where guys from the school that i haven't talked to in many years and was hoping to keep it that way. they honestly made my school years almost a living hell. anyways i gathered my power and contacted them inviting them to have some fun at the party. everything seemed to go well until the day of the party. we were having dinner it was guys talking to guys about jobs etc, and then we started talking about girls. a matter that i've had problems with for years now. i find it hard to talk to girls and the few that i've managed to keep around are always super nice. they asked how my dating life was going and awkwardly i said that i had a girlfriend even when i did not. i thought by saying this they would leave me alone. surprisingly they indeed did that very thing. i felt slightly more confident in myself cause they didn't suspect that i actually didn't have one. later that night, i decided to leave first from the party cause i had a headache and friends over from abroad staying over. 
next day i woke up to a message from a friend let's call her "lara" wanting me to explain myself. i was clueless what she had meant so i decided to call her. she explained how after i left they met up with the girls from the other side of the bachelor group and they started talking about me having a girlfriend. one of my friends (one of the few i still talk to) was interested and found out who was the person i said was my girlfriend and then contacted them asking if this was true. the other girl who she messaged said that it was a big misunderstanding because we did not indeed date. lara was furious and not like a little bit but a lot. yelling me about how i did not think of my friend's feelings etc. she told me that i would have to tell my friend and her fiance that i was lying or she would do it. i thought the best thing to do was to get it over with and call them. i apologized and the fiance understood and said it didn't really matter. my friend on the other hand wanted to talk. (and yes i apologized the friend who i claimed to be my girlfriend but she just laughed it off cause to her it wasn't such a big deal.) so me and my friend agreed to meet up in the evening. we talked a bit and then he asked my reasoning for lying which he was just nodding to. then he dropped the bomb, i couldn't be the best man anymore. this was because being a best man requires trust. i understood that i should had not done what i did. at this point my friend was crying and i was depressed. he said i was still invited to the wedding. after that we walked our separate ways. 
it's been a couple of days since that and i still feel like shit.

TIFU by lying at a bachelor party.
