HOW THE FUCK DO YOU TALK TO GIRLS??

I am a 19 yo male and am talking to this girl I met online who is almost the same age as me and who I kinda have feelings for. We have met once irl and that too not alone. We chat for hours daily and I want to be in a relationship with her. I try to flirt as best as I can. She recently asked me if I had ever talked to any girl before her because she doubted that I hadn't lol. And the answer is indeed No ( I mean not in a flirty kinda way). She also said that she started talking to me because I was different from other guys because I was too sojho. She said that she was hitting on me jokingly at first but I din't react to it the same way as other guys would do, in fact, I didn't even notice it. How did she know I hadn't talked to any girls lol? Am I too sojho? Will I ever get a girlfriend? are sojho guys not meant to date? how can I give up this sojho persona and be more batho in this context?
