So I read the sidebar and I'm a bit confused with the "do not use text message" to talk to a girl. As a 30 male I want to ask what you guys think of talking to a girl by facebook/whatsapp to set up the logistics in the current situation: A coworker is interested in me (I know that because my female friends told me), seems that this girl is already interested/attracted, I don't see her too much because she stays in another room. Nowadays we use whatsapp and facebook to communicate, I was thinking of making some comment by fb IM since she added me and ask for her number to ask her out (yes direct approach like that). What you guys think about it? I just got a bit confused of this "don't use text" kind of rule.

Thanks
