Me ( 18M), have been with my girlfriend (18F) for almost a year now, however, since a few months into our relationship, i cant help but think that i am not good enough, and that there are so many people which she would be happier with, im flat out broke, i am not good looking, i dont play any sports and im physically very weak, however she?, her family is rich, she is a great singer, she is beautiful, she has hella talents, she is smart as fuck, and more and more stuff that i could spent years talking about,

I dont want to break up with her at all, she is the person that taught me what love means and feels and i hope i can turn a better person for her, whoever i just cant get it out of my mind, and i bad for her? Am i gonna ruin her?

We recently had a "discussion", where im being honest i fucked up big, she was going through something and i tried to "fix" her problems instead of listening to her and support her, she doesnt know that i know but she went on a call with a friend in our group to talk about how i made her feel bad and stuff because of that, and honestly i just felt like total shit, i apologized ( not telling her i knew abt the call ), and told her i wont do something like that again and she happily understood and forgave me, whoever theres been about 5 times where something like this happens where i fuck up big and we just dont talk for the whole day until she feels stable for us to talk, and i get that relationships are never gonna be perfect and that there will always be mess ups, but i feel like im messing up way too much and im genuely scared to fuck up so big that i ruin everything we've built together,

So again, am i just dumb for thinking like this?

And sorry if this not the place to post something like this but im not able to post it anywhere else as it always tells me to post it in a place like here.
