The only thing I can think of is to set him down and tell him that you need
to set bounderies. Do what is best for everyone involved. Even if it isn't
what is best for him. If he and his alters have gotten their way all the time
they will always think they will. My wife tried pulling the same thing on me.
I put my foot down. The end result, she left for two days and came back
willing to talk and to compromise. It took two days for her to talk it over
with
here alters. They realised that I was always their for them and they didn't
want to loose that. If your SO wants to keep the relationship going he will
have to lurn to deal with the dissapointment that he will not always get his
way. I hope this helps and forgive me for the spelling errors, I have a degree
in science and math not english.
