Ohh I have a high school history related to that, which happened much before I started questioning.

There was a guy who I admired (I was more of the geeky-artsy guy and he was a extroverted sporty dude) due to his sheer confidence, despite he not being very smart. One day, I overheard him talking to others about having issues at home (and he also had an explosive argument with a teacher days before) and I decided It would be nice to cheer him up and maybe help him with certain evaluations and also share some snacks with him (I take friendships very seriously). At first it was okay, and I made sure to give attention to other people too as to not seem "weird". But then, two weeks later I noticed one of the toxic bitchy girls of the classroom told him "it was clear I was into him" (I honestly wasn't. He could stand completely naked next to me and I'd feel nothing) then the days later he either ignored me or had this "cocky/irresistible" approach that put me off. Then he started saying stuff like "C'mon, You know fancy me. That's okay" and I started to want to punch him in the mouth. He chose to believe her and didn't at least talk about it with me at first.

It felt like the empathy switch dropped and just felt grossly used so I faded away and he continued to drop his grades for a while, then managed to kept them "good enough" to graduate. He never said thank You once, and only gave back half the money he borrowed (it wasn't much but still).

It's one of those (many) experiences I've had that make me bitter towards other guys so I put a lot of walls and rarely let them become anything else than acquaintances, no matter how nice they may seem. I now study Graphic Design and I'm planning to do an informative material about bisexuality. Even in this day and age There's too much BS and baggage around this label, and I want to tear it down because like You it pisses me off. For bi people, for those with Ally-potential and for those like me who are or may be questioning.
