I texted him back in similar terms.
He's definitely single - not married, no girlfriend/partner lurking.
When I hadn't heard from him by today, I sent him a text asking about something we'd mentioned previously - bit better than a bland how are you etc. And no reply.
I just don't get it. If I'd not heard from him at all I'd be like ok, whatever his loss. But to hear - and several times - then 48 hrs later it all changes, its just too bloody weird.
What's worst is this isnt the first time, this is what happens to me every time! :(
