Without going into to much detail I have a sort of complicated issue. My slave and I live relatively far apart and sometimes we see other people in vanilla normal dating sort of ways. My slave fulfilled a fantasy of someone she was seeing this way by "pretending" to be his slave, for apparently all of ten minutes and she "didn't really do anything but lie there." She doesn't see the problem with this despite how much importance I put on the fact that despite the fact we see other people, being an M/s is special just for us. I'm looking for a way to explain it to her, but since she wasn't collared and it was all "pretend" she doesn't see it as a big deal. She accepts that I feel very hurt by it, but I really need her to understand and I can't seem to explain it.
