My boyfriend has cluster PTSD and while we don't think he technically has DID there are occasional alternates.

One of them is a little kid who is completely adorable and awesome and loves me so his "visits" I don't mind at all.

The other who we just call "the Asshole" seems to be nothing but a combat mechanism who shows up for a good reason but then doesn't go away. Last time he was triggered by a BAD interaction with a therapist and stuck around for days. My boyfriend isn't terribly thrilled with this character either.

We've already decided to suspend his driving privileges (long story, GOOD REASON) which I'm not looking forward to. Besides that our strategy for trying to contain him next time is to maybe pacify him with some alcohol and hope he retreats to my boyfriend's "fortress of solitude" upstairs. We're hoping that if he gets to be somewhat naughty he will stay put.

My boyfriend blacks out most of what this guy does, but this guy thinks he IS my boyfriend which is frustrating. Should I not engage and somewhat ignore him until either the little kid or my boyfriend is back?
