Hello all, thanks for the replies - he's a real life boyfriend I meet almost every day but when we're not together, issues like this arise

By chat, I mean our whatsapp chat - I left so I could reply to another person. This SHOULDN'T even be a problem but I feel like he's made it into one, he's created this problem. For instance, before I started dating him I'd reply when I could to everyone I talk to instead of it always being back to back. Now I have to explain what I'm doing, why I took a while to respond etc
