Jesus Christ - 500 bucks??? Why do you have to pay for everything?
You should tell her to get lost.
She wants to do something special for me for my birthday and invited family and extended family members, a lot i don't care for nor met probably. At first I told her I don't care to do it, but she insisted. Since I felt bad for her to have to spent all of that money to invite so many people. Days later at the day before, she goes... "so yes, you will be paying for the whole bills, since it's etiquette for you to do so, since you're the host!"
So basically, she invited me out, picked the place, invited as many people as possible out, and then change the narrative after to made me pay the entire bill. Screwed up on so many levels.
If I am inviting people out myself, then I am the host, and that way I can see it's my etiquette to pay. But not this...
Yeah, thinking I might just back out, disappear for to somewhere for bit at worst. Although that will only generate a whole set of consequences later on... I hate this really.
