What are the signs a guy is desperate for a girl?
He starts talking softer than common.
Starts buying you **** that you dont even want.

When he is checking out girls everywhere and looks at their back and merely look around for girls and stare longer than normal. Well I do adjectives of the above even though I have a g/f. But I judge those are the signs.
