The use of "myself" as an object of a preposition

[Steinkar]

"There was an ad-hoc agreement between the Lieutenant Colonel and myself." I think "myself" should be changed to "me" because “myself” can only be used after a preposition if the object of the preposition is the same as the subject of the sentence. Am I right?

[John Owen]

Well, both are objective and thus correct. However, when the speaker is the object of a verb but not the subject performing the verb, use me. When the speaker is both the subject and the object, choose myself instead.

For example,
She hit me
"Me" here is the direct object hence more appropriate than "myself."

I hit myself
"Myself", here, is both the subject and object.

Hope this helps.
