Can’t go past the talking stages

Hii I’m 21f and never had an actual bf, just failed talking stages and I don’t understand what’s wrong with me, I have been texting with this guy and it seems like we’re doing good, we share a lot of same interests but he started being dry and I’m just so upset bc this isn’t the first time that has happened to me. Maybe I’m too much, or maybe I’m not pretty enough. I’m just so embarrassed bc my younger sister got a bf before me and they’ve been together for months while I can’t even go past the talking stages. Sometimes I catch myself thinking that maybe I’m not meant to be happy in life, or that maybe I’ve done something bad and it’s karma. I’m also too ashamed to talk to anyone irl bc it’s just the casual “oh men are stupid, it’s their loss, blah blah” which I do appreciate but I still yearn for a romantic partner :(
