and still no-one will answer the question. If this was cancer causing mood swings, or epilepsy, or any other kind of disability, would it be ok to put all the onus on to the individual who was having the mood swings (which were beyond their control sometimes) to do something about it?
It strikes me from op's posts that on the whole the ds has a good relationship with the dp, and that this issue arises when he has had an episode, which while understandable does not, IMO, mean he shouldn't be living in the family home, given his moods etc are stable the majority of the time.
And anyone who thinks that asking your patner to move out wouldn't impact on the relationship is delusional. So you would all be accepting if your partners asked you to move out if you had an illness/disability which could frighten their kids? riiiight.
If this was a mental illness for instance and diagnosed as such, would people be saying that the onus is on him to manage his condition? no didn't think so, in fact people would be slated on here for being non understanding of mh conditions. Yet diabetes can cause mh issues, and all sorts of other issues for that matter, kidney failure, blindness, death, to name just a few, but presumably as with the mood swings if these things happen then it's all down to the individual because they didn't manage their condition properly.
How fortunate that so many on here seem to be experts in the management of diabetes, when it seems that even the medical professionals here are struggling.
