Dear Jane:
You are WAY over analyzing things! Remember the old adage about how to impress a man: “Show up naked. Bring beer.” We really are that simple.
So, to answer your questions (bearing the above in mind):
q1) If a guy’s efforts to get attention fails, will he show anger?
a1) Yes. But as soon as the hockey/football game starts, or the pizza is delivered he’ll forget all about it. Attention span of a dog…
q2) If he feels she really likes him, but she is refusing to show it
a2) He’ll continue trying because he hasn’t actually been rejected. Bumblebee keeps hitting the window…
a2) eventually something else will distract him, though.
q3) someone else starts flirting with him, will he forget his first crush?
a3) Yes. Until he’s alone and reflects on the fact he screwed up somewhere. Could take years for that to happen, as the world is full of distractions.
q4) He’s really passive-aggressive but acts like an “alpha male”
a4) If he’s acting like an “alpha male” then he’s probably not really passive-aggressive. Good that she’s not impressed, as he’s probably a psycho.
