"Peter lives in your house."
Translation:पीटर तुम्हारे घर में रहता है।
I believe that तुमहारा becomes तुमहारे on taking a postposition (pattern for masculine nouns is लड़का - boy, लड़के - boys, लड़के को - to the boy, लड़कों को - to the boys).
Jaisalmer is my favorite place in Rajasthan, although others are close. I was there in September of '16. So beautiful! Were you there long?
My late partner was from a village in Jaisalmer district so I've spent loads of time there over the past several years.
