I'm going to end my friendship with a close friend
Why do you want to end it with her?
Because she keeps asking me for money for stupid things and I'm sick of it
You shouldn't end a friendship over a small thing. You should just tell her to stop asking for money.
It's not a small thing, it matters. I just want to get rid of her.
Well if you aren't happy with the friendship then it's fine to end it. At the end of the day it's your decision.
