Most if not all of this " people talking about you" is actually in your head and not reality. Back when I was in HS and early college, I used to also think people would talk about everything I did . in fact, I was convinced about it. it made me stifled, anxious, and afraid to express myself . As I got a bit older, I realized the truth which is " No one gives a shit about you" . People are way to self observed to even dedicate a brain cell towards you . this is a good thing, because it means you are free to do whatever the fuck you want (as long as it doesn't' involve blowing up my PMs). So, in conclusion, stop worrying and treat her like any other girl.. Think of the fact that she knows you in real life as an advantage not a disadvantage .

Hey, first of all, you write with all these "....." just like you do in your texting - reminds me of the way that old people write emails. Makes it hard to follow, so I suggest killing it (at least in your text game).

First, you're way overthinking this, again. It shows a clear lack of abundance, but more importantly, overthinking tends to lead us to the wrong choice. You need to reframe some of this overthinking, for example, "This girl is almost certainly matching with tons of guys she tangentially knows at our school. There's no way she has the time to tell her friend in my class about every guy she matches with, and if she did, that would be really bizarre of her."

Second, your posts are a bit tough to decipher, because you're asking many questions and it's unclear what you really want. I can't tell if you want advice on "this small world" or "what to message next"? Please try to be clearer in the future, it makes it easier to help you!

As for what to message next: exaggerate what you are doing and make it a bit of a DHV, while also making the message something that moves the conversation forward.
