So I reccently started dating this one guy (online) and we talk and actually have a nice time but, sometimes I wanna get in a good conversation with him and he sends simple answers that make it akward. I do have him in this group chat and he talks a lot more there. He is a shy guy and its cute but, is there anyway to make him speak more?? Hes only barely begin to start asking me questions and I love to answer But soon after he'll start sending one word replys

How can I get good convos from him?? How can I get him just a teeny bit interested in me?? >~< Do I have to hold off replying him too fast?? (I reply fairly quickly when he send me something)

Please help >~<
Thanks ^~^
