Didn't

Are these sentences correct:
Why didn't you tell me this and went and told Sarah?
Why didn't you tell me this but went and told Sarah?

Why didn't you tell me this but instead told Sarah? (that is one possibility)

1-Do you think one can use "and" instead of "but"?


2-What if we are talking about two acts, but one was not carried out instead of the other.

He decided not to break anything and leave a threatening note in my apartment.
He didn't break anything and left a threatening note in my apartment.

Why didn't he break anything and left a threatening note in your apartment?

Hi,

2-What if we are talking about two acts, but one was not carried out instead of the other.

Yes, you can use "and" in place of "but". It is a question of emphasis. Is it a continuing thought, or is it in contrast?

This answer applies to all your other questions as well. Miriam, I believe, wrote a post on the difference between "and" and "but" recently. You might want to use the search feature to see if you can find it.

Is Act 2 in contrast to Act 1? But is a good candidate.

Is Act 2 in parallel to Act 1? And is a good candidate.

You didn't tell me. But you told him. See the contrast?

You didn't me and instead you told him. You told someone, it just wasn't me.

It is a question of what you want to emphasize.

Hope that helps.
