Am I not pretty enough?

I liked a guy and he pretended that he liked me too, he flirted with me but rejected me when I approached him, he said I am too naive and innocent for him.. I was heartbroken as he was the first guy I felt attracted towards.. After a year, I dated another guy for a few months and I came to know that he was seeing multiple women simultaneously.. I honestly have lost all my confidence.. Why did that happen with me?
