When a virgo says 'you can do better'?

Funny you mention this. My ex bf's mom was a virgo and thats exactly what she told him about me behind my back. "you can do better" HA!. I dont put myself on a pedal stool but I was a damn good gf... anyway to the point virgos are perfectionist. So whether in relationships or how they push themselves things have to be perfect... saddly deep inside they are insecure but you surely will never know it or see it quickly because of how high they carry themselves.
