So I got with three girls recently, and they all seem to like me. But I have this self esteem problem where I think I’m a piece of shit sometimes. I was also talking to this pretty girl and she seemed to like me, we exchanged instagrams and to my surprise she followed me back. My point is I don’t know how to text a girl well or talk to her in a way that moves the interaction forward. I know this is vague but I can make things clearer if you ask. Any advice?
