First option: She really wants out. I don't really believe this option.
Second option: She is trying to pick fights with you to make it easier on her to justify leaving...."We were fighting ALL of the time...." But you've stopped her cold there. She turned off the music, you didn't bite. She gave you a WTH look when you did something nice with the glass of wine. You ignored it. Then she wants to change plans that you worked hard on and you said "do what you want....this is what I'm doing." And remember, she came with you.
Don't worry about looking at her phone. Do what you have to do, this is war. "I want to run away." That could mean one of two things, in my opinion again. A.) She literally wants to run away and get out of the marriage. B.) She is so confused because you have been so great lately she has no idea what to do and needs to be alone to figure it out because you're doing way too well in confusing her. I believe option B.
Don't lay it on her yet, the ultimatium type questions: Do you want to stay or go? Give it some more time. I mean seriously, WTH else do you have to do right now?
