The reason the LGBTQ groups are telling you to leave your sib are because they’ve gone through similar situations and they know how this story goes. But is it worth trying to talk to your sib one last time, not because it’ll change anything, but because it will give you a bit of peace as you go through grieving process later. You’ll be able to tell yourself honestly that you gave them every chance to be a better person, and it was their failure that they decided not to.
