If
Contrary to popular belief,
Inuyasha did not think of Kikyou often.
When he did,
He would start at where it all went wrong.
If
He had trusted Kikyou
If
She had trusted him
Then Naraku would not have been able to take the jewel,
Or at least they would have realized what was going on
If
They had
Then
He wouldn't have been pinned to the tree
Kikyou might not have died
He wouldn't have slept dying for fifty years on a
Fucking
Tree
If
He hadn't been stuck on the damn tree
Then
Kagome would never have woken him up
Would
She even have fallen through the well?
Would
She….
But
Inuyasha didn't like the thought of a life without Kagome
So
He didn't think of it
