Can you please help me with this?? PLEASEE? (LONG)?

First off, you were being pretty rude to your aunt, inviting her and then un-inviting her, and still expecting her to drive you and the friend you offered her ticket to and not wanting her there. You should sincerely apologize to everyone (mom, aunt, friend) for putting them in an awkward situation. Go with your aunt, have a great time, and find something cheaper and closer to home that you can do with your friend. Your aunt also probably feels pretty hurt too. Just try and look at the situation from everyone else's point of view. And also, don't snoop on your mom's phone, that is incredibly rude.
