Saw her at the store tonight

Rounded one of the aisles and stopped dead in my tracks when I saw her. She was on her phone and I quickly left the aisle to checkout. It’s an Aldi, so it’s a small store, and as I was leaving after checking out she was in line, looking at me. I left the store and drove home with my hands shaking.

It’s been almost three months since I last saw her in person. I didn’t know the last time I saw her would be the last time, until now. Part of me wishes I appeared stronger, or unbothered or something. Another part of me wishes I said hi. Another part wishes I didn’t go to that store at all.

Now I’m sitting in my room waiting for her (or, more honestly, myself) to break no contact. It feels like I’m back at square one again. I have never been so shocked in my life to see someone. If any of you have had this happen, how did you deal with it? I’m going to the gym later to try and clear my head.
