Hi FOB,
Your situation reminds me of my past back in the hostel like 6 yrs ago. There were lots of Nepalese in that university and I saw that some girls and boys fought for penny as well. But I had very good roommate with whom i transferred and stayed together like 3 years. My hostel made me realize that if you want to study and have your own life where no one bother what you do, live with few Nepalese as much as possible and try to stay with foreigner next door.  I lived with few Nepalese and when I went to finish my undergrad, I lived with foreigner. it was my good experience. Coz, I don’t want to hear who gona clean today? Who gona wash dishes or had to explain to all that I had exam tomorrow and pls lower the voice….

Well my suggestion for you is to leave that place and stay with others or alone. Don’t worry abt the relation. The only things matters is how satisfied are you living with them.

In my experience, its hard to find a good roommate but not impossible. But, when I think abt my past, I had super coolest roommate and I m sure I wont find such a roommate again..
