Spouse with DID (multiple personalities) - Any experience?

My husband within the past two years with diagnosed with DID. Now while the diagnosis was an answer to the the questions and worries we have dealt with over the years, it was adjusting my standards and boundaries that made the alters more comfortable and so on that got waters muddy. They've seen me broken down, crying, not wanting to be touched, and my husband himself is aching so badly with "him" (alters) causing me so much pain and distress. One has gotten him into legal trouble multiple times over the past 4 years (10-12 yrs mentally) and one acts like a class clown frat boy sorta talking to SO many women over multiple apps and websites. This behavior in turn has resulted in hangouts (no biggie, trying to let them have some time)....which eventually resulted in adult activities with 4 different women.

I know it's not my husband himself doing this behavior and cheating and so on, but it's a *** of a hard time sometimes to separate it mentally. It's affected me where I hardly want said activities with him, which in turn is affecting my husband (physical touch love language)

Point of all this, any advice ?

Any others out there with spouses that have DID and such? Experiences?

Even if you don't have it or any experience with it, general advice would be helpful too. Thank you in advance ❤️
