The rest of the night was not so great. Wendigo told me that he thinks we need to take a break, possibly a permanent break. He thinks he's being noble, taking a step back from our physical relationship because he thinks he's being unfair to Runic Wolf. Whether or not we'll be able to convince him otherwise remains to be seen, but for now I have to accept that our relationship is changing.
Right now I'm just sitting with my feelings. It hurts, but we're still best friends and taking the physical part of our relationship away won't change a whole lot. Still, it really sucks because it was completely out of the blue.
