This feels like quite a weird situation. Most the time if someone bothers to initiate they want to have a conversation, right?
This is a guy I dated briefly earlier this year but we went our separate ways because I had to relocate for a job.
Well, he’s on my whatsapp and I can guarantee he’ll initiate saying something once every few days. He usually says that he hopes I’m doing awesome or something like that, I usually thank him and ask him what he’s been up to, he says he’s okay and is glad to hear I’m good. And that’s it. He doesn’t give me anything to go on or ask any questions, so why bother initiating conversation at all?
