There’s something really appealing about a low-maintenance girl who can hold her own with all your guy friends. But a girl who has no girl friends whatsoever should set off warning bells. What is it about her that prevents her from being able to relate and befriend other women? Is attention from guys so important to her that she insists on surrounding herself with them at all times? Is being the girl who hangs with the boys a too-integral part of her identity? And, even if you aren’t the jealous type, are you really going to be okay with her hanging out and confiding in other guys, night after night after night?
