First off the man is acting like a director trying to control every aspect of what he considers his. ie daughter. Right now he has no concept of others.
As far as OW I would put that thought so far out of your mind right now because he is definately a very unhappy man or he wouldn't be acting this way.
You need to determine where to draw that line and fight for yourself and D. I found myself in this same sitch 12 years ago with my kids mom. She tried much of the same tactics even removing youngest from his grandma who was daycare and not letting me know where he was. Many times she pushed and I finally said I wouldn't be pushed into the corner without fighting. We ended up in a trial which she lost and looked the fool.
Don't be bullied! Stay as calm as can be, but not a doormat.
Once again he sounds like an angry miserable stressed out kid right now. File it away and pray for him. Must really suck to be in his skin.
Stay strong and my prayers are with you.
