Those apps are toxic and will kill your confidence unless you are really good looking. Girls have hundreds of matches for showing up. But they are so shallow so they filter out most of the guys and most likely miss a lot of people they would really like. :)
Actually I would go as far as saying that social media has made girls think they are some kind of a super creature, deserving of thousands of guys just admiring them. Lols.
My plasma 6 desktop has absolutely stunning icons, and im like you - I like proper icons that look more interesting.
Try plasma 6, I'm sure those icon sets are also much more complete. :)
