With all of this said it's incredible that people are able to post on social media often. It's a crushing amount of mental energy. You could chalk it up to others not being critical thinkers but that just feels like a subconscious way to insult them and simultaneously compliment yourself.
I had to tell my girlfriend when we first started dating that I usually see her texts within moments of getting them. However if I don't respond soon then I'm not trying to play mental games, build tension or whatever. I need time to formulate a response and type it out. When she sees me text others she is appalled at how difficult it is for me. I can coordinate plans, answer a short question or relay facts with no effort. The second it becomes a conversation or small talk I just lock up. This is with everybody not just someone I'm attracted to.
