At my wits end with arguing dd's.

[Meadowflowers]

Just that really10yo, 13yo and 17yo. They argue all the time and they are so nasty to each other. Unfortunately they have to share a bedroom as I have ds as well. I just don't know what to do with them and I am constantly playing referee to their nastiness. Any suggestions?

It really isnt fair on the children to blend families when you dont have the space for it.
It is possible to have a relationship without living together.

Yes, I do have to wonder why you moved in together when you clearly didn't have enough space?
