i’m really starting to hate my best friend

so we became online friends with L in 2020 through a game and have been friends since then. we got really close, we’ve helped each other through break ups, her parents getting a divorce, etc. i even invited her to our family vacation in 2024, in response i went to Malta with her and her dad.

around a few weeks ago i slowly started to feel some sort of disgust about her actions. she broke up with her boyfriend because he cheated on her and i kept telling her for weeks before the relationship ended that she shouldn’t be with him as her mental health was getting worse. at the time i thought this break up would help her realize the importance of building a relationship on a solid foundation is better than fighting for a relationship in the beginning all the time. but i was wrong, as she became obsessed with every single guy she talked to, was constantly asking me what she should text them so they reply. she was partying all the time and i pointed out how she shouldn’t make out with 5+ men at every club and get so drunk she doesn’t even know where she is. it seemed like she took a break from drinking and she started to get better, then came the text that she kissed 2 guys from her friend group (she’s the only girl there)

but what really caught me off guard was the fact that she started criticizing my financial situation. i’m a high school student and working throughout the summer for the first time because i plan on buying myself things. i befriended a guy and we talked about renting out an Airbnb to get away from the stress and relax for a few days. with full of excitement i told her about this and she started bringing up how it’s a waste of money and why do i want to spend so much money (my part is only
\~60€ for the trip). and as if it was not enough, i told her i wanted to buy a pair of shoes i’ve wanted for a few years but wanted to get it from my own money. she told me i was an idiot and how do i plan on going on vacation with her if i spend my paycheck (i put around half of my salary into a savings account).

before i went to london, which was 2 weeks ago, i ask every friend of mine whether they want something from Sephora or some kind of skincare. i asked L and she told me that she doesn’t need anything. but when i finally arrived to london she demanded i purchase her victoria’s secret panties and also get myself a matching pair. she transferred the money to me on revolut to buy her one but i didn’t want to buy one. i gave in, bought myself a pair and also one for her. then she demanded me to buy her some souvenir.

today she asked me for money to which i replied why she needs money as she’s working just like me, even having more work than i do.

i don’t know what to do about this situation because when i bring up how i don’t like others sticking their nose into my finances. am i a bad friend for sometimes fighting the urge to block her when she does things like this?
