ex girlfriend/mercury retrograde

So my ex girlfriend broke up with me 3 months ago. I cut contact with her, she popped up a month ago to say she was sorry she was rude (but wasn't rude) and that was all.

Now I didn't know much of mercury retrogrades until recently and apparently it started February 6th, I "ran" into my ex February 7th. She showed up at a concert she knew I was at, texted me asking if I was there, long story short the following week after she re-added me on Facebook, would text me first etc. Brought up old stuff from our relationship right down to how many sugars I put in my coffee.

From my reading I understand during this time confusion is likely, and exes reappear (as she did and I'm definitely confused) so after a week I messaged her saying I'm lost on how she popped out of the woodwork to contact me. She said because she missed me but understands if I didn't wanna talk to her. I said I missed her back but I don't like being friends with exes because I don't like the thought of seeing them with a dirtbag.

She stopped texting me after this. I can't help feeling like she took me the wrong way that I wasn't interested in her at all (retrograde confusion?) and that I turned her down. She did wish me a happy birthday a few days later but still wasn't talkative. So I wrote her a message to clear the air, state how I do feel but I am confused on her intentions, but if she wants to grab a drink with me it's her call, no response yet.

So, any thoughts on what I may expect after the retrograde? Will she reach out again or will confusion be settled finally because I do want her back.

If it matters my dob is 2/19/86 and hers is 1/25/92 so it's compatible to the signs the retrograde is apparently going through. Thanks for you insight.
