It's about subtext. Women communicate covertly via subtext. You were using a lot of it, maybe without realizing it. The subtext was screaming "I want it, and I want it now!". Best way to avoid that is to never use humor in any kind of "texting", meet face to face as soon as possible. Body language, facial expressions (including micro-expressions), and tone of voice make all the difference in the world.
But it could have been a fake account and then it doesn't matter anyway unless they want you to send a bitcoin account number to a big tall guy named Suzi in Nigeria.
