I agree with what's been said so far. It looks like she might be having an affair, or at least considering one. I guess it might work for you that she is still in the same house but it might also drive you nuts as you'll be wondering about her whereabouts constantly. Nonetheless, whether it's for financial reasons or otherwise, at least she is still around and that can give you a chance to make small changes which can be noticed and to GAL. This in itself might make her realize what she is walking away from. Do stuff with friends, go out, dress nicely, change your cologne, get a new haircut, make her wonder what you're up to instead of you wondering what she is up to. It's much easier to do this while she's home.
It does sound to me that you are pursuing a bit and since she's already said that she felt more relaxed when you'd started to give her space, I think you should go back to that and let her initiate contact, even if you know she's home and awake. I think that the more you intrude in her life, even with innocent gestures, the more you might make it difficult for her to feel relaxed around you and she might eventually opt for leaving the house.
This is where I am now and believe me, although it make it easier to detach (somehow), it also brings its own new set of problems and worries.
