The shenanigans sound like young high school stuff that married couples don't do.
Other than that, I am not clear on who is filing what.
IMO no newly married couple (you're newly married if you have less than 5 years in my view) should have a roomie unless you're broke and then, only a relative.
And a roommate like that needed to go the first time she got involved in ANY WAY IN ANY of the arguments...let alone the rest.
it's not done. Period.
So what is your goal now?
