Well, if you only exclusively want girls to chat with, that sounds to me like you are wanting some sort of an online dating relationship going. ('cause if you weren't in this for an online dating relationship, then why would you only specify girls???)
Anyhow, IMO, those don't work out so well, but you might have better luck. (I actually know someone who married somebody he met online and it worked out very sh***y for him, so

)
