I realize that by virtue of being an incel you are inexperienced and I don't expect you to know stuff about women ...and I'm not claiming to be an expert either. I just want you and everyone reading this to know that revealing your feelings for a girl in writing, be it a letter or an email or text, is never going to work.
the part of her brain that could possibly feel attraction toward you (I mean, it wont feel attraction, but it's the part that would feel it) cannot read. So she's thinking about the real you (which hasn't turned her on) and reading these words about feelings and stuff - that's actively turning her off.
"b-but genma women love romance novels!" Yes, but here are two things: (1) when they read those novels they are imagining chad, not a guy who is "such a good friend." Sure, if a woman was attracted to you, and you ascended, then it'd be fine to write her a letter. But if she's not attracted to you; the letter isn't going to help. (2) aside from the imaginary chad in those romance novels, a huge part of the fantasy for women is, quite frankly, rape. They're reading about a chad that is so overcome with feelings that he risks jail and death to force himself on her. That's their fantasy.
A random letter from a "just friends" guy that she has no feelings for ...isn't the fantasy.
I'm sorry you're going through this. I was in high school in the fucking 1990s and everything was different but even I blew it with cheesy letters and shit and even back then in the "good old days" before unchecked hypergamy, it got me demoted from friendzone to creepy stalker.
If you ever have a chance of ascending, you will do it by somehow (don't ask me, I have no clue how) being face-to-face with a girl and poking her in that region of the brain that actually feels attraction. Not with a letter.
