There is a reason people keep telling you to get a L involved. You need one.
As far as the "stop trying to control me" issue is concerned, you need to just keep reinforcing to her that this is NOT about her and you are NOT trying to control her, it is all about your right to know the whereabouts of your kid. How would she react if you did the same thing next time you have access to your child. She is denying you the right to see your child. She should not have that power.
I have a hard time believing that one parent can simply take the kid from the family home without the permission of the other and go to an undisclosed location, without any consequences whatsoever. You need to seek the advice of a professional on this.
Keep standing up for yourself through your actions, even if she tries to tear you down.
Also, how is the job hunt coming along?
