Melbourne, anyone up for catching up?! 🙋‍♂️

To protect my girlfriend's privacy, I've pixelated her face first. I'm studying in China, and we met during winter break. She said she's studying in Melbourne. We've been happily in love, but recently, something seems off. Her replies are brief, sometimes she even reads and doesn't reply. A couple of times this month, she disappeared at night, saying the next day she drank too much to respond. Although I truly trust my girlfriend, I can't help but have doubts. Any friends from Melbourne know her? Please message me privately. I just want the truth. Should I perhaps let go of this relationship? She lives in this apartment, quite spacious, but is it a studio or a new building? Facilities are great, with AC, fridge, microwave/oven, stove, etc. Bills included! Conveniently located near Chinatown and Victoria Market, shopping's a breeze, and it's super close to school – just 180 meters from RMIT's doorstep and only 800 meters from Melbourne University. Walking to school is a breeze!
