Are you an asshole? No, but you are not as smart as you think because a smart man would recognize that your girl is taking interest in your job and wants to not only learn about it but interact with you while she does.
Also, and let me preface this by saying I have an advanced understanding of the market as well, if you were as smart as you think you are you would realize that you can ABSOLUTELY learn from that series, just maybe not in the way you first think. You can learn your GFs understanding of the market, learn more about what the general public is learning when they try to gain info making it easier for you to anticipate panicky or under informed investors patterns, and I’m sure there will be at least one sentence in the series that will make you say “huh, hadn’t thought about it that way.” So you’ll absolutely learn something. But you’re not an asshole.
