An old host who discovered the system was with an ab***ve ex when they discovered the system. Our ex was also a system and the host was constantly comparing us with them. They were kind of pressured to admit they were a system and some alters were influenced by our ex telling us who they had to be as they were forming. We have no idea who is real and who the host made up to please our ex now the host is long gone. We don’t know how to deal with this and it’s really distressing. Now that we aren’t with the ex we feel like it would be a good time to undo all of this but like how do we know who’s real? Any advice would be much appreciated.
