Was talking to a girl on and off via text messages. She hardly ever initiated but always responded. I thought she is not interested so just forgot about it. A month later she initiated for the first time and we talked a bit. I never initiated after that so it went dead. Then one day I got a message from her that she is changing her phone number and included her new number in that message. I didn't pay much attention to it and thought it was a mass message. Newayz today, after 5 month she pokes me on Facebook.
What should I do? Directly text her on new number or message on the Facebook first?
