Well, the title says it.
The sentence is from a manga, where a boy lives together with her very lazy aunt, so the boy has to take care of laundry, cleaning dishes, cooking etc. while she's drinking beer. He gets angry and she explains that's it's a pain to do all that stuff (cooking, cleaning etc) on her own. Then he replies "僕が来る前からこーだったんですが?"
Does it mean "Then how did you manage it before I came here?" or does it rather mean "So were you like this even before I came here?"
Thanks in advance for the help! :-)
