And for her,she is calm cool and collective like none of this even bothers her... My take is she has done this so many times before it prolly does not bother her the pain she has caused me.
If you can locate other protection orders she has sought against earlier relationships then you might have basis to state she is abusing the system by making a habit of making exaggerated claims and even framing her prior lovers into saying things that could get them into trouble. Have you read
Dr Joe Carver's articles on
Controllers, Losers, Users and Abusers?
She is pushing your buttons. She knows, whether consciously or unconsciously, how to trigger your 'righteous indignation' over the unfairness of it all. Whether that man is or isn't her brother-in-law is inconsequential. Police don't care who he is, court won't either. If you ranted to the officer about that they will see you are likely headed to trouble, hence the warning not to contact her or else you would get in deep trouble. Yes, you could have asked the officers that just she could enter to get her things (with officer present of course) since likely that man didn't have a real need to enter with the officer present.
Remember too that this is a judicial system, not a justice system. You might get fairness from the system, but you can't count on it. But you still have to play by its rules... .obey the order, let go the outrage, be smart, don't do anything to trigger the officials to clamp down on you and move on emotionally.
So, all her things are out now? Then there is no need for contact ever again. Do not seek resolution or closure form her, you won't get it and trying there could prove to be a dangerous trap for you. Closure is something you will have to Gift Yourself. End the chapter, close the book and toss it into the deep blue sea. Don't look back.
Trying to make her pay, trying to make everyone agree with you how terribly she has acted, trying whatever... .odds are it would only complicate your current legal issues. Yes, never confirm that what you said was a threat or even a hint of a threat. Sort of the way you would warn someone sitting on a tree branch not to saw off the branch since they would fall. Sadly, in today's world it is getting harder and harder to get people to look at the intentions of the one person talking than at the perceptions of the other person hearing.
I repeat, try your best to quietly end the current legal problems with the least damage to you legally. Then... . Let Go. Move On. Don't look back.
