Am I ugly if I've never dated?

Like an ex best friend(S) of mine had always been in relationships, guys absolutely love her, and soon enough I kinda got jealous, how come I was just her backup when sh^t went wrong, there was a point where I really liked this guy and she gave me hope that he would say yes, but when he didn't it really hit, yeah I know not everyone can like you, he just said he wasn't looking for a relationship and ended up dating (S) (like 2 days after), I mean it shook me, and she apologized to me and said that she was sorry and made me feel guilty when she said that if I wanted them to break up she would do it, but that wasn't how I really felt, like why am I just the ugly best friend? Yk the song fat funny friend? Like sh^ts so relatable, like the whole song I can relate too.
