It is a babystep and one of your goals. Continue to be pleasant around W. Say good morning, goodnight, smile, make small talk. Even if she doesn't respond much keep doing it. Eventually she will start to notice some of the changes you are making. Keep your expectations low. Some days she may respond more and then other days she may be non communicative.
