Have started seeing someone, early days but going swimmingly. He’s attentive and thoughtful, really seems to like me, had a few lovely dates and made further plans etc. However I sent him a couple of WhatsApp messages yesterday around 6pm and he was online all night and last seen on WhatsApp at around 2am and he hasn’t even bothered to read them (I can tell from the ticks they were successfully delivered but not read). AIBU to be pissed off? Or am I over-reacting (I’m good at that!).
