Met a chick through a mutual friend, got her number and her instagram. We spoke a little through WhatsApp over the course of a week. Asked her if she wanted to grab some coffee through WhatsApp, she never opened the WhatsApp message and started messaging me through Instagram instead. Took this as a clear lack of interest from her part, therefore I stopped messaging her and moved on to other chicks. Now she just sent me 3 fucking selfies of herself through Instagram. She is obviously playing games, should I just keep ignoring her?
