Don't assume what W will do. You said in one of the first posts that her complaint before when you DBed was because she felt you were too controlling. Once again this is fresh so I doubt after finding out about the A that she went, filled out an ap, and got an interview. This was probably in the works before she found out. Be happy for her and give her reasons to not want to leave. Think of it this way, as you stay together, having more money will make her feel more accomplished and will give you both more.
Stop always thinking she is doing this to move out or to kick you out because it is self-loathing. The plan for the worst, but hope for the best is true, but this is still new and if you keep thinking and worrying about her about to kick you out, it will show and it could be your demise.
Be positive. Take your beating, but don't think that everything she does is to kick you out. It might be, but worrying about it is not going to help any.
