Rude shocks

Today, I was reminded, yet again, of how our friendship failed and became the shitshow it is today.
I'd thought I'd be done with reminders. Everything that once connected us has ended, there were no more obligations. But I guess some ties take a lot more time than 6 months to be broken. Up to recently, I still get asked by my mutual friends or my parents, "how is _?". I just say "good" and change the subject. Because I'm done talking about everything that happened. I've moved on and I don't need my headspace to be invaded by the bad memories.
Today's reminder was worse than the previous questions. It began innocently. I had to check my flight details and send them to my dad so that he was aware of my plans. Then her name popped up as my emergency contact. I promptly changed it, but alas, the memory had been triggered. I was reminded of a time where I'd made bookings for both of us, be it flights, tours, concerts, etc. I'd etched in my head her full name, DOB and all the details. I'd list her as my emergency contact and vice versa. But those days are over. I had thought, after 6 months, her name wouldn't be anywhere near my paperwork, bookings of any sort. It was a rude shock, but funnily, I didn't feel pain anymore when I saw her name. I just felt confusion, I felt perplexed to see her name with mine. I felt like it was a mistake that had to be corrected. I guess that was a good sign. It doesn't bother me anymore, it doesn't tear my soul apart to know that she doesn't care about me like she used to. Thank goodness.
