Who upset the teenager?

[Zeroperspective]

A and B were married and have now been separated for over a year and a half. Person B left due to years of abuse which Person A denies happened. Since seperating there has been an ongoing pattern of abusive messages followed by love bombing, Person B has not gone back since they left and charges are pending against Person A for harassment from approximately 10 months ago.

Person A made threats of violence towards a friend of Person B and who is of a different gender to Person B. Person A does not know this friend and has never met them they are just aware that the friendship exists.

Person B reported these threats to the police but given a complicated history and knowing the pattern of abuse they asked the police not to arrest but to warn Person A to stop or charges would be brought.

Person A's teenager was at home when the police arrived and is now having nightmares that Person A is going to be sent to jail.

Who is responsible for the teenager being upset?

YABU Person A who's behaviour warranted a police response

YANBU Person B who should have ignored the threats and not got the police involved knowing there was a very high chance the teenager would be home.

Apologies it's long I was trying to give enough info so as not to dripfeed

Person a. They and they alone are responsible for their own behaviour.

Person A, without a shadow of doubt.

Person A

However person A sounds like the kind of person who never accepts responsibility for their own behaviour so is probably blaming person B.

Person A.

Person A is responsible if they have committed unlawful acts that led to the threat of imprisonment.

The only way they could not be responsible is if the allegations are false.

Person A.

But teenagers are emotional about parents, so may not understand until later.

I think there's something adrift in my brain because I find these Person A and B posts really hard to follow! However it's fairly clear that Person A is to "blame" here as it was their actions that led to police involvement. Maybe this is the wake up call the teenager needs, that adult relationships are complex and can be unpleasant.

There are 2 sides to every story. With the story above person A.
But no doubt if person A told the story it would be different.
Poor kid.

Person is responsible for their behaviour and the consequences of it.

As some of the comments have surmised, Person A (my EXH) is indeed trying to pin the blame on Person B (me). I will never convince him otherwise as it has been a long running theme that he is always the victim regardless of the circumstances. I am hoping to show the teenager though that this is victim blaming by his dad in the hope that he doesn't turn into an abusive adult like his father.

The allegations are not false as the threats were made in writing so further proof that my EXH brought any action upon himself
