Leftbehind,
thank you for sharing so much and being so open about what sounds like a really hurtful situation.
if its ok to ask? How come you are certain your wife has DID? are you a health care professional? Has she been officially diagnosed? If neither are true, am wondering how, if you live outside any kind of mental health world, you would think this were the most likely illness behind your wifes behaviour?
Sorry to come in late and ask questions you may already have answered, but it is important with something like DID not to dive in and assume everything is true or happening to your wife. Hope that makes sense and hopefully in time you will find someone to confirm your fears.
Otherwise am thinking any kind of discussion about this with her may well end up badly for you. Terribly for her, with little progress being made. DID takes a long time for therapist or pdocs to diagnose , so would consider that route for confirmation and support.
take care
Julia
