A guy I've dated casually before just emailed me a URL site out of the blue. I didn't bother to check it out but replied him with a "thanks, how are you?" since we've not been in touch for 2 months or so. He wrote back that he's seeing someone now, and asked if I am. Perhaps I'm sensitive but somehow that email exchange felt weird, like he triggered it specifically just so he could let me know he's snagged someone.
