The girl i am dating is perfect except that she is really, REALLY slow

Pretty much the title. Completely my type, loving, caring, beautiful, cute, amazing sex, cares about my interests, got into mma bc of me bc i do it, likes to talk, is a good companion. Except for the fact that she really has not been blessed with intelligence. When watching a movie she will literally ask me things that are being openly shown. The other day while watching batman, she asked when the time bombs are exploding. The time bombs were exploding on screen while she was asking. She is rhetorically basically illiterate and needs extra explaining for basically every word that contains more than 2 syllables or stems from from greek or latin, such as "fictional", "dominant" or "indecisive" it feels like she has not been part of the same world that i have been until now, and it's a bit shocking. I am generally very patient and kind in all of my explainings about basic stuff since i really like her and i like seeing her learn but sometimes this all is just really frustrating, since i am someone that likes to go on analytical breakdown rants about pretty much everything i'm interested in She's really gotten to my heart as apart from that she is a really good companion... BOTTOM LINE (READ BEFORE COMMENTING) Dont really need advice, just wanted to talk to someone about it
