I mean, it is what it is. When a man says to you that he has to "watch the volatile stock market" and, therefore, can't hang out with you during the week and then doesn't follow up and doesn't offer to make any plans for the weekend.. well, that just means that a man is simply not that into you.
Now, I don't care how busy that man might be. The world might be crashing all around him but if he really wants to see the object of his affection, he will find a way. So while he says that "watching the volatile stock market" is his prerogative for this week, I am not naive enough to buy it for a second.
I mean, I often work 12-hour (sometimes 12-hour-plus) days, write for two blogs, write articles for a web site and am currently learning how to design a web site of my own and still... I have time for social obligations.
But it is what it is. And it's one of the reasons that I don't let myself start opening up my heart to a guy if we'd known each other for less than 4 weeks.
