"No one but you" similarity to "God"

she didn't break up the beatles....she was one of several factors that helped to highlight cracks that were already there

the relationship between lennon/mccartney had not been great for about 3 yrs

some of  the contributions to the breakdown were:

the influence of non-band members - wives/girlfriends
friends with ready supplies of mindbending and paranoia-inducing drugs
management choices  Klein rather than Eastman
george and ringo getting sick of the arguments - and disappearing (on skiing trips and such like)
lennon's heroin addiction resulting in his invisibility for huge chunks of time

but the overriding key nail was Klein's near-bankrupting them...that was the final nail...and the Macca's need to break up the band to prevent them going broke (listen to the abbey road medley - it's all there)
if you've watched the Let It Be rehearsals film you can actually see the band breaking up
they had worked together almost continually for ten yrs....george was developing as a writer and wanted more room to express himself, lennon and mcacrtney were heading in different directions musically and were sick of each other

fact is, that as much as i have always love the beatles...lennon mccartney (and those they trusted) behaved like arseholes at the one time in the band's existence when it could least be afforded

the one's who came out of it with their self-respect intact were George and Ringo

Another factor was Brian Epstien death and the lack of his presences during 'The White Album' sessions

            then again you could always joke that the fab four broke up cause of the New Maccer as he 'died' in a car crash during Sgt Pepper

lennon and mcacrtney were heading in different directions musically and were sick of each other.
==================

I think this is the main reason, they just grew apart, It happens, normally to really close friends or siblings.

The Beatles are the prime example

1. Why going in business/ working with you friend isn't a good thing
2. Why band members are often renowned to hate each other

Further to IsleOfRed's thoughts, by extension, Queen is a prime example of:

1) The whole being greater than the sum of its parts.
Your mileage may vary, but in the end it appears the band was known to argue democratically in the studio and the result was top-notch work. I think it's fair to say the arguing was a necessary part of the process that kept the standards high. Certainly their solo careers never matched the commercial success of the band.

2) Take a break but don't break up.
By the early '80s, after Hot space and its tour, Queen took its first real extended break in about 10 years. No big announcement, no public criticism of fellow band members, just them going off to do solo projects. They all wanted to try different things and were probably a little tired of the arguments and grueling tour schedules. The key was that they didn't end Queen, they just took a rest from it. Then they came back to Queen when they were ready.
