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
