Woah, there was no need to have slept so much, lol. Anyway to answer your question:
The Boss shows up automatically after day 68 as long as you've completed all of Stacy's quests and after unlocking the laboratory.
It's impossible for your save file to have a glitch/bug.
However, it is interesting to me since the last thing I want is players to get stuck.
Please send me your save file and I'll gladly take a look.
In general though: Are you stuck somewhere? Visit a bunch of other girls.
The coming update I will remove all vague hints and make the journal 100% spot on.
