Do you have any idea how much upkeep that body requires?
This girl isn't hanging out playing video games with you. She ain't even lying in bed to watch netflix on a sunday. She's definitely not going out with you to bars on a friday night. She's out at 6am every morning on the track and spending her free time (the tiny amount she has) doing meal prep and probably studying. She goes to bed at 9pm. She's a fucking athlete. You don't want to be in a relationship with an athlete.
I'm not guessing here. I've briefly dated athletes. Dullest dating experiences of my lifes. I'm sure they found me lazy and apathetic every bit as I found them square and one-dimensional.
