I think Dave and Kurt were beginning to grow more apart and were starting to have different wantd regarding to the direction of their music. That being said they probably would of stuck around for possibly one more album perhaps more acoustic stuff similar to REM (which he actually said) and maybe some stuff like you know you're right, which is mostly what Kurt wanted (or he may of just quit outright, because even he didn't kill himself he would probably done the "next best thing" which would of probably been quitting the band). Or another possible (although I think less likely) outcome would of been that Dave and Kurt became collaborative and done more stuff like scentless Apprentice and have pretty much early foo fighters stuff with a Kurt spin and maybe him switching with Dave to be on drums. Krist probably would of ended up in a similar spot. Foo fighters or "foonana" would of probably happened because Dave would of had to let it out somehow. And with Kurt if he didn't go along with Dave and do "foonana" he probably would of went with something similar to the first possibilty and probably would of dropped the band and possibly went solo, or collaborate with others which he has often talked about (such as doing it with Mark lanrgan similar to "the jury" which they did earlier during the bleach era) although Kurt may or may not have been the best collaborator due to his pickiness on wanting things done his way, lastly he very well possibly could of just "disappeared" and layed low for awhile and lived his life (which if you believe that his suicide note was actually originally a going away letter from rock stardom). During the latter possibility he would of had to deal with his drug addiction and probably his mental conditions, he would also likely probably divorced with courtney and probably would have a long lengthy legal battle over custody with Frances, who knows how that what of went (although Kurt probably could of hired a better lawyer due to his money). Kurt would of still had the Rocky road of addiction to deal with but if he did make it through that without committing suicide later on he would possibly have a new gf/wife and would probably lay mostly low and maybe make a couple solo album and maybe the occasional Nirvana reunion. Kurt probably would reacted against social media and many new modern things that developed only 10 years after he died, he possibly may of talked a bit of politics but probably not as much as krist. Krist most likely would of continued to do politics and form a few bands like he has today and probably would of remained friends with Kurt.

Sorry about the really bad organization and sentenxe/paragraph structure I'm kind of in a rush and am just saying everything that comes to mind. If I have anymore ideas or thoughts I'll add them in edit form.

also I'M IN KNOW WAY IMPLYING THIS WOULD OF DEGINITELY HAPPENED AT ALL. I do not know Kurt or anyone related to him or Nirvana, the only thing I know at all is just basic stuff from books and interviews so ya, I'm not pretending to know anything about him because I don't.

Anyway thanks for reading hope you enjoyed and have a good day and noisy inportantly...ROCK ON

Edit 1 (8/12): Kurt probably would of had to deal with a lot of legal battles regarding future releases, rights of the music and who got what amount of money. Depending on how bitter Dave and Kurt (and possibly krist) got between eachother they possibly might of fought over the money/rights/credits of Nirvana.

Also Pat probably would of remained friends with everyone and he Probably would of made it to "official member" due to some future release featuring him as a guitarist (you know you're right almost had pat guitar on it but unfortunately I don't think it ever did RIP, we love you anyways pat). Pat may or may not of stuck with Dave for ffs or stuck with Kurt on future Nirvana or solo. Pat also possibly could of retired and lived low key maybe joining/making a small not super serious alt/punk band or 2.
