Input: Text: this fu all blew up in my face a few hours ago.  this semester i am taking a physics class and my lab group has been meeting up a couple times a week to study. there are three other people in this study group, john, anna and this pompous knowitall rat faced dweeb named nate. nate is one of those people who puts other people down to make himself look better. he also has a huge crush on anna.
after listening to nate's snide comments about how much smarter he is than me. i noticed that he got very uncomfortable and visibly annoyed when guys talk to anna. so i decided that i was going to start flirting with anna. so over the last couple weeks when our study group meets up i have been flirting with anna. i started sitting next to her at the table(where nate usually sits), buying her coffee, and joking around with her. and it worked, better than i thought it would. i could see nate squirming with anger when i made her laugh but he couldn't say anything about it without looking like an asshole.
now is a good time to probably add that i have a girlfriend, and while i have no plans to ever pursue anything with anna i did not tell my girlfriend about my plan to piss off nate by hitting on his crush. and here is where the fuck up begins. so when our group  met up on wednesday we were discussing our test grades and comparing answers when nate made some comment that really pissed me off, so as we were leaving the group i asked anna to exchange numbers with me(right it front of nate, fucker was pissed). again i have no plans of cheating on my girlfriend, i just wanted to piss nate off.
so today my girlfriend and i were watching some youtube video on my phone when i get a text from anna. so of course of gf asks who anna is and i tell her she is a girl in my study group, then she asks what she wants, so i open the text (infront of my gf) and its anna asking if i want to go get some drinks with her. my girlfirend was not happy, accusing me of cheating on her. so i told her about how i've been getting back at that nate guy by harmlessly flirting with anna who he has a crush on to make him mad. this did not make things any better. now she thinks i'm cheating on her and i am an asshole. she stormed out of the house saying she is so angry at me she can't even be in the same house as me. so now i'm sitting here writing this post wondering if i still have a girlfriend.

TIFU by hitting on a girl in my class out of spite
