I would suggest that you go back over to Newcomers and read Sandi's postings. I believe you will find some answers in her postings concerning the WAW taking responsibility for their actions, etc.
Whether your w is a WAW or a MLCer, the methods/techniques we use will be the same, i.e., giving them time and space to figure things out. As to whether they take responsibility for their actions/behavior will be up to them and sometimes we do not discover that they own up to those actions until the very end.
Right now, your focus needs to be on you and how you plan to move forward w/life as you know it at the moment.
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.
