I wasn't going to say anything but since your comment brought "real" relationships into the mix, there's a lot more pressure on the man to not come off as "needy", "desperate", etc. and the difference between seeming as such or not can literally mean the difference between a relationship and suddenly no relationship and a restraining order, etc.
I don't want to sound unequal but the stats are there that men have a higher rate of becoming stalkers, etc. so in our society men try our best to be aloof etc. and ironically "minimize" priority of a relationship (if we're lucky enough to have one) so as not to suddenly find ourselves on the other end of the fine but very, very, very significant line.
Back to Trek, Spock has logic but he also has intuition. If he did dump his entire career for T'Pring, chances are she STILL would have dumped him for Stonn, and he'd have a restraining order on top of the hell he lived through in Amok Time. As it was he barely came out unscathed and just dodged, thanks to McCoy, life imprisonment for killing Kirk under plak tow.
T'Pring was perfectly ok with Spock going to jail for his 2 century long half-Vulcan life and living the rest of his life in guilt and horror that he killed his best friend. That is a MASSIVELY disproportional retribution crossing into un-Vulcan emotional revenge over her arbitrary beliefs that Spock prioritized his demanding job over her some years ago. We have no indication at all that T'Pring was involved in McCoy's efforts to save Kirk's life.
