Am I not enough?

Saw several posts on here about body language toward a girl who is hot and a girl who is average. Most of the guys said they would treat the girl they weren’t into like a normal person, and give slightly more attention and respect toward the attractive one.

I’m not sure what you all are smoking. I am curvy, pretty face and dress well but in public situations guys and girls never want to talk to me. I’m always trying to start conversations and people will answer but not ask follow up questions. No one is interested in having an actual conversation.

Am I not enough? I’m not sure what to do differently.
