Whoa! Look at all these comments!
Are you like... still in the same place or are you chilling somewhere else for a bit?
Anyway, hope you either work it out if that's what you want... or don't if that's what you want. For what it's worth, I've got some experience with couple's counselling and have found it pretty good. It's just easier to have that extra person to mediate and help draw things out that need to be sorted with. It definitely sounds like your fight didn't really resolve whatever the root of it all is.
How did your housemate deal with all the shenanigans? I pretty much would have left for days.
