Well, there are many like this one (called "ghosted"). To ghost
means (as a verb) to end a personal relationship with someone by suddenly and without explanation withdrawing from all communication. This is one of many (but I'm going to share about them all because they're part of the 500 rejections).
So, it's about a "ღ桥" (不完美女孩). For a long time she didn't send any message. I sent her some:
过年好！ Meet well the Chinese Mouse Year!
Happy Valentine's Day! (情人节快乐！)
今天我可以给你words of wisdom ..." (the last one was some philosophy of life).
Months of fruitless "communication". 100% ghosted and I had to delete this contact.
