My aunt saw my texts about her while reading through my phone? Now she's mad at me, how do I fix this? Help!?

It wasn't her business to read your texts, it was an invasion of privacy. You're entitled to your opinions, and she hurt you and she brushed it off when you confronted her. Respect is important, but it has to mutual. She shouldn't feel entitled to your respect and your caring about her feelings if she isn't respecting you and your feelings. Tell her how you feel and that she will only get your respect if she does the same. She needs to understand that you're hurt by her actions. Try bringing another adult into things so she realizes what she did wrong. Also, apologize, but only after you're sure she will.
