So I saw my ex today at another group event. This time I had decided that I would only say hello to her and then distance myself. When she showed up, I was surprised that she approached me and said hello with a big smile, asked how I was doing. Then I stuck to my plan, I didn't speak to her and went out onto the patio to hang out with some of my friends while she stayed inside. eventually she came outside and was making eye contact with me. A little later people started to go back inside until it was just me, her, and a friend of ours. She then started asking me questions about how I was doing, how my music was coming along, how one of my close friends was doing, etc. I played it really cool and answered everything, joked a little, got some laughs out of her and asked her how her music was going. After a while I had to go so I politely got up and said goodbye to my friends who had come back outside and then looked at her with a smile and said "it was good to see you". She smiled back and said "you too". I know it's not much but I felt pretty good about everything as I left. I wasn't upset or distraught at all like I was the last time we saw each other. I'm trying to not get my hopes up and move on but we'll see what happens next. I've not sent her a letter yet, I've decided to wait for her to make the next move. She knows the ball is in her court still.
