Am I beautiful?

Aminah
So recently this guy I've been somewhat dating left me for a younger girl. And my ex did the same thing. It's making me feel as if since I don't have the best skin, long hair, nice big butt and say.. Ten I'm not good enough for them. So I went on this app and my name was up there and these are somethings people said and someone even entwined that fact the the guy left me for a high schooler (we're in college) is because I'm ugly. So I'm questioning myself. Am I? Do I need a big butt? Clear skin? And the girl seems chill and that's what I wanted to be like to him but why can't I be? I embarrassed him... Because "I'm ugly". And he made me look stupid... Because "im ugly"... Right?
