It's probably a combination of both IDU. Just keep doing what you are doing. Sleeping in "our" bed has to be seen as a good sign, right? I know I would welcome it myself as a positive step, just remember not to get too overzealous or you will push her away again. That has got to be hard as I would want to throw my arms around her and just cuddle for a while, but I would have to fight the urge.
Good luck IDU and keep up the good work! You are doing great.
