I'm in a similar boat. I absorbed German really easily, but when I moved on to picking up another language, my brain constantly switched between the two, even during an intensive study course that was basically several hours a day exclusively in one. I tried beating my brain into the right shape, but no amount of effort made me anything but embarrassing in anything other than my native tongue.
