What’s the protocol for keeping in touch with old plates and a recently ended mini ltr that parted on good terms?

  1. Ended a 6 month mini ltr on friday due to her moving away for med school (500 miles away and set up before we met) She’s been texting me and i haven’t replied because i know i’ll most likely never go out of my way to see her again unless she moves back.
  2. Old plates keep hitting me up and pinging me to see what’s up.

I’m mainly concerned on how to approach the girl from the mltr. I want to see her again someday down the road as she was super cool and displayed good ltr qualities such as cooking for me, submissive and feminine, doing favors and even making me clothing on a couple occasions. She has never brought up us being in an actual relationship but has dropped hints about us being together subtly in the past (saying in bed “our professions usually end up together”)
