I was not here for “stone gate” that was during one of my long breaks from PC.
T’s can be so weird though. I am very thankful that my current T has stated clearly from the beginning that his boundaries are fluid based on where he is at the moment, where I am at the moment, and where we are at the moment. I tend to think of boundaries as written in stone and freak out when they change (it has usually ended badly for me). So hopefully the moment has changed and T is truly comfortable with their offer to let you switch stones.
