I know this feeling very well. But consider: they may have met another partner or something life-changing may have happened that makes them unavailable right now. When these things happen, I find it helpful to think about my life and the things that prevent me from continuing a conversation. They are so varied and most have nothing to do with the person I’ve been chatting with. Still, I wish people were a little better with saying, “Hey, can’t talk now. Hopefully later, OK?” But we’re not good at rejection or rejecting with kindness. Sadly.
