  I have a hooker friend that trying so hard too look classy and superior. She do sex for money and recently get married with a old guy. She show off. She like to bring me when she is shopping to show off how much she spend and she always pay for our food. She like saying thing like "i'm rich..", "let me pay, i'm rich", "I only want rich man", etc
  We both in early 20 and meet at school. I come from tbh a quite rich family, my father have few company (she know, and that probably why she being friend with me, last time we go holiday to other country, all expend my family pay. But my parent raise to be "humble", my pocket money is like most of my friend, i never brag and i try to be kind and all of that kind of bullshit).  I actually never feel any pressure because i know i have more than her. 
  The things is, she like to bring me down. She have a bad self esteem and i think that's why she do it. She like to say and treat me like i'm dumb (she drop out from college after a lecture get angry to her because of her stupidity, marry her loser sugar daddy, and she trying to say that to me? LOLS ) And you know what i do? I will try to kill her with kindness (which is easy because i'm known as sweet innocent girl)

So here some things i do:

-her: you are a failure
  Me: hahaaha whats failure about me? I just finish my degree and i'm going to master soon. 
How about you?

-her: my get ** dolar every month.
 me: wah, really? Is that enough for you? *act like i'm feel bad for her*
(fyi my father earn so much more than her husband, her husband income is only twice of money i spend every month. My father have two kids, and he always saving more than he spend)

-her: am i ugly
me: yes *with a honest and kind face"*

-her: *trying to brag about how much she spend for a bag"
Me: why you spend so much? your husband income is only xx etc *show her i'm worried*

-her: you are bimbo
Me: no lah *act like i don't care
few hour after
Me: i know you are a prostitute HAHA
Her: bla bla bla no
Me: really you are not? Good because it's disgusting lols

And so many more thing happen but that's basically what i do every time she try to act shitty and bring me down. I will try to destroy her with a kind face (why being hysteric or violence when you can left some kinda permanent mental problem with your sweet voice) 
Everytime i do that i can she hurt in her face and she trying so hard to act cool. I know i hurt her. I don't feel bad because i think i'm some kind of justice warrior.
I can easily just avoid her because our friendship is little toxic, but somehow she entertain me with her pretentious act (like look at a bitch trying so hard to pretend she is a rich classy lady, but in the end she is still a dirty bitch. It's funny. I feel more superior than her. I feel good,) so we still meet and hangout sometime.


AITA? What should i do? Is she deserve it?
