I met him online and we were chatting and getting on. Sending literally essays to eachother. Anyway, the other day he stopped replying at teatime (5ish), he left my last message on read.. So I sent him a message saying have I been ghosted with a host emoji. And all I got back was, no sorry something came up! Me being a girl, if I really liked someone I wouldn't have just left them on read and not replied. I would have told them somethings came up. Does this sound like an excuse or am I over thinking?
