I doubt that a great deal. On this post alone I have seen others respond to you who have not agreed with what she is saying and others respond who do. There have been talks with her not on this network as well in relation to her anger and in other filters that we have all been privy to.
You are hardly the only one who has made any sort of effort. What precisely do you think it is when you are invited to the various gatherings we've had? When we have checked in on one another to see how one another is fairing? When exactly is it that you have made an effort with the others? No, one person will not invite you to certain things but I fail to see why you would wish to engage with her considering her attitude with you. But I also fail to see why that means you cannot have reached out to the others to do various things with them.
And I wasn't aware that all communication was to happen on this network and not with people face to face. Nor do I believe one should blame children for their apparent uncertainty about what to say to anyone.
Walk with your friend, but please cease deluding yourself of this apparent belief that no one actually cares.
