I don’t understand advice welcome

Ugh it’s maddening what the hell? How can one person make me so crazy? Crazy in a bad way. Everything seems to be going good and bam back to reality. I guess I really don’t understand men at all. I need help figuring it out what is going on. He flirts with me and says some really cute things and he is sending all the right signals. He asked me to meet him at some festival but I could not make so we have to reschedule. We were talking about how he calls girls dude and then he said he calls his girl dude. His girl? Who says something like that to a girl your trying to date? This is not the first time he has mentioned her either. This what I have to look forward to? Him talking about is girl? He has two kids with her and they live together but he says that they are friends with benefits and he is not tied down. Well it sure sounds like he is tied down. Come on really who says stuff like that? I don’t understand so he wants to be friends? That’s fine but don’t touch my arm don’t tell me you missed me don’t say if I wasn’t working there you probably quit. I can’t really ask him anything because we are not really anything right now it would scare him away. I’m just really confused and need advice what should I do? Does he like me Yes/ No? Maybe so? Should I just move on and forget him? I’m just trying to understand him. I don’t really want to give up on him.
