H, Give her lots of room and space, no questions, no expectations. Right now, in her mind, you are just that...room mates. She's shut down and until she comes to grips with the issues from her childhood, she'll continue to run. It's not you at all, but all about her.
For now, do your own thing, continue being supportive, but treat her like a room mate. No expectations, no questions..no pressure. Allow her to come to you when she's ready to talk and really listen and validate what she says/thinks/feels.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
