She got the offer to study abroad, but she wants to break up with me 💔

I got the offer yesterday and we broke up today. When I first told her about studying abroad, she supported me, but I could tell she was unhappy. I knew her thoughts, she didn't want to limit me, but she also didn't want us to be apart. To make her feel better, I found a studio specifically. Our start was dreamlike, we met on the street while travelling and she was buying duck necks. I was attracted to her when I passed by her and it was love at first sight. Later on, we had mutual feelings and naturally ended up together. We talked for two years without ever arguing, her personality is really good, we both met each other's parents, it really wasn't easy to get to this point. Yesterday when I told her about the offer, she didn't say a word and it felt like there was a big distance between us. Last night I secretly looked at her phone and found she was sleeping while looking at our photo together, I also saw her chat with her best friend. Her best friend said long distance is already hard, let alone in a foreign country, and not knowing if I'll come back or not, nothing is certain, and it's a waste of time, so she advised her to break up. After I saw this in the morning, I was already feeling bad, and after seeing what her best friend said, I became very agitated and my attitude towards her was very bad. After arguing for a bit, she calmly said to break up and she's already packing up and leaving. What should I do now???
