Why did Tobe stay the whole time with Emily... but then left?for love

Presumably, in Faulkner's "A Rose for Emily," Tobe stays
with Emily until her death because he needs a job, or out of a mistaken sense of
loyalty.  But, really, that is just speculation.  We can only
guess.

Before Emily's death, the speaker really couldn't
elaborate on why Tobe stays without ruining the surprise ending.  And there's no reason
to explain his staying until the body upstairs is revealed.  There's nothing unusual
about his staying until we find out about Homer.

He leaves
in a hurry, of course, so he doesn't have to answer questions about the body or take
responsibility for what's been going on in the
house.

Once Emily dies, the only thing revealed is that
Tobe skips out the back door.  This, of course, heightens the suspense as the reader
wonders why he so urgently leaves.

As far as is revealed,
no, there is no love, at least not romantic love, between Emily and her
servant.
