Well, at no point during this entire process have I stopped missing her. I've made a lot progress in moving on compared to how I felt weeks to a month postbreakup. I was a mess. She still finds her way into my thoughts but not as consistently. I've tried to understand her motive for seeking how I am but I'm sure it meant nothing other than maybe she just wanted to say hello.
It definitely put her back in my mind though. We had a talk like we hadn't been NC basically. It was awkward on her end trying to gather words and keep the conversation going. At one point she said she would call me right back but needed to go see her brother for a second. I used that opportunity to cut the talk short and sent her a "it was nice hearing from you" text. Kept it short.
All the advice I've read online says you must keep contact to a minimal if you want to heal. That's what I want.
