I have a couple times. The last time was a couple years ago with someone I met online who I was getting to know but didn’t like after the first date. They asked if I felt like watching some movie and I didn’t respond and they didn’t follow up. Tbh, I probably would’ve answered if they had sent a second text. I guess I avoided telling them the truth but it stuck with me like a pebble in my shoe and I feel bad thinking about it.
It wouldn’t have changed my stance. A follow-up message would’ve pressured me to let them down easy seeing they were still interested, but their silence felt indifferent.
