Why wont a guy talk to a girl first?

A lot of girls make the mistake of getting a guy's attention through a personality other than their own.

This will hurt you in the long run, because he wanted to talk to who you are impersonating, not who you really are.

To get a guy's attention,

try discussing something he looks like he likes.

If he's wearing camo, and you like hunting, or have a familiy member that hunts, begin a conversation pertaining to that.

Or just pick a topic that's interesting, he may chime in if he wants to conversate, or just speak a few Words.

Stick to open ended questions, which may lead to a longer conversation, and determine to each other what you're all about.
