The reason why you feel a bit in a quarry about the deal is because you're only 18 years old. If you have something for sale, you instantly become a "business man" which means..."money talks and bs walks". The money talked and you sold the car. The bullshit walked and he doesn't have the car. Simple. You can't get emotional (i.e. texting, returning calls, being overly friendly, apologizing, etc) because people will take advantage of you.
