You must put the idea to rest that you and your W are still a team. Other than co-parenting it doesn't matter that she could get the info faster - you are on your own. Embrace it and learn to love the freedom that offers you.
You contradict yourself. You agreed to HELP your W with the job hunt out of "niceness" when chances are she is pushing this and acting interested in you improving your job situation to be in the best shape possible for a divorce. So, if she wants you to date other women why not do THAT out of "niceness" to please her? Do you see how ridiculous that is?
Next time she says "we have to do this or that" tell her there is no we, you want the bills/finances split and you want off her insurance and you have decided to get your own.
Be firm about that then go back to being mysterious and act manly until you learn how to be manly.
