I'm hoping for the best. It is odd, but sometimes people like the status quo because they are uncomfortable with change. Perhaps your boss notices that you're suddenly getting compliments and wonders if you'll now be a threat to her job. By micromanaging she might be trying to make you second-guess yourself. Or maybe she's reiterating to you in no uncertain terms that she's the boss.
It is wise of you to ask her point blank via a paper trail.
