Why sometimes Virgo (girlfriend) doesn't return my messages?

Virgo's personality: When you care about someone, you like him very much, because Virgo people are delicate and insecure. If that person gives her a great sense of security, she feels that she doesn't have to stick together every day and contact often, and she will trust the people she sees and do. Virgo's love is gradually released, and it is not felt until you know it.

I'm a Virgo, so is what I gave him.
