You should stay "in the know" about your legal rights/options as well as potential apartments. But not necessarily pursue these in an effort to make the first move. But knowledge will only help you.
Consult a lawyer to be informed, but until things change (by your decision or your W's) no need to take action.
Keep an eye out on apartments (what they cost, what is available in your area, how often is turnover, are they safe (for kids to be there) etc.) but don't sign anything until things change. Keep your browser history clear for your research. You're not trying to start anything - but you should be aware of all your options.
