Was I really this oblivious, or was she just being friendly?

First of all, English isn't my first language, so I used AI to translate this.

27/M

10 years ago, I was a 17-year-old virgin high school student who was completely and hopelessly in love with B, while being absolutely blind to everything else going on around me. I was deeply in the friend zone with her.

B had a very good friend, H. H was my classmate, and we had always gotten along really well. Our interests were pretty similar. In 11th grade, H and I became really good friends, and she knew very well that I was absolutely crazy about B.

H had already been in a relationship for years at that point, but she didn't mind spending some closer time with other guys either. I don't really want to go into details about that, because I still remember that girl very fondly.

Honestly, H was a very attractive girl, but I was never sexually interested in her. Because I was an idiot.

We spent a LOT of time together, both at school and after school. At some point, we became each other's confidants.

There was one moment when she pulled out her phone and showed me a video of herself giving a guy a blowjob, saying something along the lines of, "Look how small this guy's dick is." I'm not gonna lie, we laughed our asses off.

And now we get to the important part.

It was already near the end of the school year. I remember because it was extremely hot, and H had her hand wrapped in a bandage for some completely irrelevant reason.

We were killing time at a bar after school (Eastern European things).

At one point, she went to the bathroom. A little later, I got a message from her asking me to come help because, due to her injured hand, she couldn't pull up the zipper on her pants.

So I went in and helped her properly get her pants back on, and then we went back outside.

It took me TEN YEARS to realize what was happening.

God damn it. I was an idiot.

After that, I don't remember her making any other attempts. What I do remember is that, at the graduation party in our final year, we made out pretty intensely.

And that was basically the end of my story with H.

We haven't spoken since.

Was anyone else this hopeless as a teenager?
