But in any case, it is disrespectful and distrustful to show the chat records of two people to a third person.
If you confirm that she has been sending chat records to her best friend, it's time to stop.
Not having a definite view, or showing off too much, or taking your girlfriend too seriously, are all immature performances.
It will be very tiring to associate with such a girl.
And you don't know when she will be M, and you count money for others.
Therefore, such a girl is not worth continuing to associate with, and you can gradually alienate. If Yan value is ok, it is your favorite type, you can invite her to dinner and ask her to sing, but don't talk too much, let alone have a deep chat. You can treat her as a vase and playmate, but don't be a girlfriend, let alone get married.
Since she likes to give the chat record to her best friend, you can call her directly or have a voice chat on WeChat video. Anyway, don't make material for her.
