My question is, am I really responsible if someone kidnaps her between getting off the Uber and getting into our apartment complex?
Only if you were involved in the kidnapping, like paying them to do it.
Is she trying to guilt trip me into thinkg her anger is justified or am I really a horrible, kidnap-facillitating bad person for missing a few texts?
She is trying to guilt trip you for missing her text by using emotionally ever the top hyperbole which is not gaslighting. Gaslighting requires intentionally lying about something that did not happen to make you question your own experience.
The ruling explicitly states that those things on the record are not admissible if they were not through some public form of communication. So his phone call to the Georgia governor would be inadmissible even though it is currently public knowledge since it was originally a private call he claims was official business.
His public tweets would be admissible.
