Should i be mad at my gf?

So, me(24m) and my gf(22f) love eachother very much, just to get that outta the way, tho last night when i was up a bit longer then her, i started thinking and began to upset myself, because i realised she never really goes out of her way to show me that i am important to her, i know i am, but only through very detailed cards or words, not with the tiny imoportant things such as i do

I almost always cook nice dinners for her, buy things for her, physically and verbally show her that she looks good, is sexy etc, always help with anything she might want, and always do what she wants to, because these things are just what i WANT to do for her, but i realised i rarely get the same treatment

Another important part of it is sex, i have a high libido and she has a low libido, i dont mind waiting a bit longer for sex, but it frustrates me that she's not able to show me in the meantime that she like thinks im attractive and such, because she does, but struggles with showing it. It just really makes me feel like she doesnt actually think im attractive, even tho i know she does, the feeling still lingers, should i be mad at her for this? Its affecting me throughout the day
