Here is the way I see it, he isn't happy if he is trying to scam you or not that is irrelevant what is important to recognize that this has now become an adult situation. You should speak with your parents and work with them towards a solution. Now for some reason that is not an option since they would be upset because you sold it I would still recommend telling them what happened. Being an adult means having to take responsibility no matter what happened there is no shame asking for help.
