I love your summing up @SheldonesqueTheBstard.
I'm so disappointed in Liv and Jackson.
It is like she feels that her and👄 are the power couple or summat because they are in love
I agree with this completely. It's clear from what Liv said prior to starting this, that she lacked confidence and self esteem because of her appearance and unsatisfactory relationships. Now she's got Jackson it's as if this has flipped from insecure to arrogant! Like being successful in a relationship gives her a raised status 
I think she would benefit from some work on how she judges herself and others.
