dinner?

what does it mean when a guy asks a girl out to dinner?
what does it mean when your ex-boyfriend asks you out to dinner?
and what does it mean when he mentions it to you three or four times in one day and then the next day asks to see if you could squeeze him in between work and a meeting that same night?

now i'm not reading too much into this, am i? but it sounds like someone may have changed their mind about not wanting a girlfriend. i'm just not going to deal with it until after atlanta.
