Okay, my dude, why are you acting puzzled about her wanting to go outside when you've both been imprisoned in that house for most of a decade—which is why her story of wanting to do drugs out of going crazy from restlessness was plausible in the first place?
If you had the ability to go outside, you should've offered to let her outside at the soonest moment possible if you cared at all about her emotional well-being. Tsk.
