what should i do if my gf wants to break up because i focus too much on my academics? am i overreacting?

i’m 20m, a college student-athlete, and i really need some advice. my gf (20) and i have been together for 1.5 years, but we go to different colleges and live in separate dorms. we usually only see each other on weekends, but i still drive to her campus around 3x a week to spend time with her

she told me she wants to break up because she thinks i spend too much time studying and training instead of giving her attention. i tried explaining that i’m doing my best to balance everything and that i want to work it out, but she says long distance just doesn’t work for her anymore

now i’m completely distracted and stressed, especially with a ton of final exams coming up. i feel like i can’t focus on anything. i don’t know if i’m actually doing something wrong or if she’s just done with the relationship
