He won’t compliment other women
He gets nervous if a woman so much as asks, “Do you like my haircut?” in front of you. He won’t speak to or even look at other women in front of you. If his friends are going on about how hot some chick is he pretends to not even notice her. This is usually because he has something to hide! A man who knows his intentions are in the right place feels safe speaking to other women in front of you, and even complimenting them. He knows where the line is drawn, and he knows he won’t cross it. Men who do cross the line, try to stay as far away as possible from that line when you’re around.
