Was this girls reaction appropriate?

I posted this in another section of the site too but I wanted to ask again here.

Long story short, I was dating this girl for 10 months. We moved very fast. Fell in love in just 2 weeks. Relationship was going so fine until last week.
In December, it was her birthday. She likes expensive things. For her birthday I took her to an expensive restaurant, and I got her a bracelet. The bracelet wasn't expensive, but it was a thoughtful gift because it had like a jewel in it that when you look into it, you can see our photo together.
She complained she didn't like the bracelet. Said it wasn't expensive enough. She also complained that I didn't do enough organisation for her birthday, said I could have done more organising and put "more effort" in. I am not someone who goes out a lot, and she knows this, but she still complained about both the dinner and the bracelet.

Because I loved her, wanting to make her happy, I went and bought a designer handbag, but because Im not the richest guy in the world, I went and got it from Marketplace instead of directly from the store. It was described as brand new, had an authenticity card, I've never bought designer before so I didn't know the risks. It still cost 5 figures though. When she asked where I got it from, I wasn't transparent about it because I knew she would have been upset. Fast forward 2 months later, she took it to the Dior store, they told her it was fake, and she immediately dumped me over text, on the spot while I was at work. I was so heartbroken. She blocked me as well. Because Im over at her house every week, I came over to talk to her about it. She lives with her sister. Her sister immediately began swearing at me, verbally abusing me, and because she wouldn't let me talk to my girlfriend, I had to leave. The sister also called the cops as well. I tried to apologise but neither of them accepted my apology. Was this an overreaction, or an appropriate reaction?

I got scammed on the handbag cause I've never bought a handbag before, didn't know the risks. So i wasn't aware that it was fake.
