My fault of hers?

Ok, so I wanted to talk about something that's been on my mind for a while. So before I found myself out as gay I had a girlfriend a while ago and we're still friends but ever since we dated there has always been something in the back of my mind. I like to write and read and learn (everything but math lol) and she literally can't comprehend someone who likes to willingly write and learn. So because of this she kinda "hates" me and bashes me for it I try to laugh it off but sometimes it actually stings. She tells me I shouldn't be working so hard for grades that don't even matter (because our middle school grades won't be counted in college) but in reality I don't think I'm doing that much For example we have an essay to write max 5 pages and I wore all five and still had more research to put but I couldn't fit it in. I decided to write about Malcolm X and worked hard to get my research done while she hadn't even started hers and it is due tomorrow and she's shaming me for wanting to work hard because I also stay after school to work on stuff too (willingly) like our science project she knew we didn't have it done and didn't come to school to help me finish it the day before it was due so I worked my ass off on that project I might as well have said I didn't even have a partner since I did all the work and then she came back to school the next day and complained about it which she didn't have the right to do.

So yeah am I working to hard? I seriously find working and researching stuff for school kinda fun since I can learn a lot. Or is she just not putting in enough effort? I mean she already got held back. i never went to 6th or 7th grade because of personal family problems but I'm not failing every class but to my lack of 6th and 7th grade knowledge.
