I triggered a fatty by doing nothing. It also started to negatively influence a friendship. I have a (male, human) friend who's very proficient regarding anything technical and we often work on old electrical or mechanical stuff just for fun. He likes to teach and I like being taught, it's an awesome and, in my opinion, very useful hobby. A few months ago, he found his first girlfriend. She's obese, I estimate her around 5'3'' and 200 pounds. At our first meeting, I tried to be reserved, but friendly, in order to find out a bit about her habits and general character. She was outgoing and confident and I thought that it was too perfect of a personality, especially for someone who shows clear signs of lack of restraint. Some time ago, I broke up with my long-time boyfriend because he's more or less unable to develop interest in anything. He was a nice guy, but being passive and un-curious is like a death sentence for me. The activities with my friend help me to get through this, but there's no romance involved. She, on the other hand, is a bit like my boyfriend was; only interested in her own stuff and quite unable to enjoy new topics (like the mentioned tech stuff). I learned that with time and it was a first red flag that emerged from the ground. After she learned about my breakup, she started to become more reserved towards me. Fast forward to today. My friend and me were stuck in traffic after working on some things and since I'm going back to the site tomorrow, he asked if I wanted to stay at his place for the night. No problem, normally, he lives closer to the site and there's really nothing going on between us, except our mutual hobbies. Nice as he is, he asks his girlfriend via messenger if it's okay if I stayed at his house tonight. Her reply: "You better have a GOOD reason for this." He showed me the message without saying anything. We were close to a train station, so I said that I just take the next train home and he didn't need to worry. He replied that it wasn't the first time she got jealous, but it's getting more and more extreme. I thought that my new availability may be a factor, my interests may be a bigger factor, and the biggest factor being that she was fat and I was not. So, there I have it again; a fatty hides its insecurities behind a wall of acting confident, but I'll be fucking sorry if I set one foot in its territory. Which I did by doing nothing. Now I'm back home and really don't want another important connection to be ruined. Especially not by an obeast who just started to rear a really ugly head. There's still no romance involved, but he really deserves better than that.
