Many reasons.
The biggest reason is that i unknowingly reject or show disinterest immediately towards girls who approach me for conversations and hung out a little bit with me in my school years.
They ask should we hang out, I say "Yes", I then walk away thinking we gonna hang out another day sometime.
They ask about me, I just answer or keep focusing on whatever I was doing, they stop eventually.
They say they like me and I say I like "insert X" totally other thing.
The second biggest reason is that outside of school and those few interactions when women try to hang with me I have only talked to women for school projects and now when Im 34 years old I have only talked to women at work, about work and some small talk of course, but thats it.
I have spent 80 percent or more of my total free time just playing PC games from ages 13 to 30 years old or so.
There are other reasons as well on top of that, so you can imagine.
I personally would say that once I'm more "grown up" now the biggest reason is that there clearly are certain "lines" or "ways" to "talk to women" as an adult. If you do not follow those "lines" starting from the first impression and "Hellos!" you will never have them as your girlfriend.
Its like a very complex "Dating sims" or "Choose your path" games when you try to get relationships going in a school setting or something like those weird anime games.
But instead its real life with endless options and no restarts.
Impossible in my opinion.
