You asked if it was possible for them to keep in group gossip away from men. I cannot speak on the app because I have no personal experience with any of that shit, only second hand information. But we both know women love to complain about shit all the time. But they never actually want a solution, they just want to bitch. I think this is what is going on with you and your two single friends, but they don't have their own men to dump this shit on so they are using you for this purpose to a degree. If you don't believe me, thats fine. I don't know the details of your life so I am speculating here. But I would ask Mrs Cad her take on this, since she presumably also knows the two women in question. I bet her perspective would be very interesting, especially since asian women are far less interested in drama and bullshit than most women.
