You need to tell her "This is what I need," and then list out what you need. Add "Whether or not you feel you able to provide that is completely up to you, but after all that has happened I've decided that this is what I need going forward."
Either she can provide you with that, or she can't, and you need to come across like an "That's okay -- I get it. Maybe we can get back together at some point down the road" type of attitude.
Or, if you want to be more blunt, I'd just say "You're testing me, and frankly you haven't earned that yet -- not even close. You asked me what I needed, and I told you. If you can't do that, please just let me know so I can stop wasting my time. Neither one of us are getting any younger here."
