I need an honest opinions

If a guy what's a serious relationship can anyone tell me how would you know? I'm talking to this guy for more than 6 months and we had our up and downs. We got into a fight over social media, but now we are trying to work things out. We are not in a realationship because we are still on the "talking stage" my friends keep telling me you guys should of just been in a relationship but I told her idk he has not ask me out. Can anyone tell me what to do I'm feeling a little confused?
