She is not vegetarian if she eats seafood. It is a meat. It's just not awesome meat like beef, chicken, and pork.
You know what she is though? A pain in the *** person that keeps going between eating chicken, seafood, and is mostly vegetarian as well as a hypocrite.
This girl drive you insane. Just move along. Seafood is meat. Her making this argument that it's not meat to her and is seafood and that she's still a vegetarian.
DUDE run. She'll never be happy unless you go along with her demented logic meaning you have to accept bigger contradictions as she grows. Like, she'll decide to be Vegan for a few weeks and denounce you for eating honey because you enslave bees.
Then the next week she'll not be Vegan and eat seafood. Then she'll tell you it's not meat, but you need to buy her weird crap like natures oven bread because it's vegan bread.
Listen man. Just freaking run. HIGH MAINTENANCE... Danger Will Robinson. Danger. You'll have to start eating fake meat corn dogs and veggie burgers and making extra dishes for her all the time so she can have seafood which is vegetarian while you no longer get steak.
Just get out of there while you can bro.
