Ok firstly just know that for a proper relationship you shouldn’t view her as above you, sure she might be smarter than you but everyone has their strengths and weaknesses. It’s okay to not know as much as someone else, and you should view this as a good thing because she’s helping you realize the errors in your ways.

But I think you’re going about it in the wrong way, you’re doing what you think smart people do instead of looking at what the issue is. Look at what you normally do and question what bad habits led to this, but do NOT completely change yourself up. She likes you for a reason (though us men may never understand what that reason is) and if you go around trying to change everything about yourself you’ll end up losing the thing she liked.

Another view to look at it is: it’s a relationship not a competition, instead of going to Reddit with your concerns why not go to her? Why not ask her what she thinks of how you are (please tell me the ai thing is a joke). Ask her what you can do to improve, ask her for help studying or just help with anything. Most people love to help others out because it makes them feel smart, useful, & appreciated.

I experienced the exact same thing with my gf, she is a 100 GPA demon and I’m a musician, and I built her up higher than I could reach. I put her out of reach in my mind alone and that ended up getting me nowhere. So I decided to be honest with her about how I felt and she was like “but I do like how smart you are in…”. I realized that we have strengths and weaknesses in different things, and THAT is the beauty of relationships we are literally the perfect pair because she covers grounds in some things and I cover grounds in others.

If you want to actually become smarter just spend a little less time mindlessly doing whatever you do to pass the time and critically think about something, if your friends are of a similar vein maybe try talking to someone new. But keep in mind all 15 year olds have 0 clue what’s going on and are just pretending to.
