Delayed but furious reaction

Had the most bizarre evening yesterday.  We had first directions appointment on wednesday and it took until yesterday for her to react.  Apparently I was thrown out of court as the judge didn't agree to the request for a s7 welfare report.

It all kicked off after the children had been put to bed by me, as usual, and so I go downstairs to get some supper.  She arrives in kitchen having had 1/2 bottle wine and lights up in the kitchen as I am preparing food.  She normally smokes outside and this feel like deliberate provocation.  I then take food through to living room away from her to watch tv and eat. Se follows me through and turns off tv. Each room I go to she follows.  I eventually go upstairs and find children still awake so try to get them into bed.  Now after 9pm.

Come back downstairs and find she has removed all the tv aerial cables obviously to stop me watching tv.  Tries to tell me that tv is broken.  I go to read a book trying to avoid her.  She keeps following me from room to room - apparently she is quite entitled to do this as she lives here as well!

Then I am challenged on where is the £150 from my mother sent for the childrens  music lessons which they don't want to do now.  As I refuse to tell he she rings my mother to demand where it is.  Don't hear this conversation  but she then comes through to the room I am using as a bedroom saying my mother wants to speak to me.  Doesn't leave the room but proceeds to literally scream abuse and obsenities at me while my mother is on the phone.  Mum hangs up but still the tirade continues.  She is wanting a reaction but I simply ignore it.  I really feel she wants me to lash out or move out, neither of which I intend to do.

Eventually at about 10pm, quite pissed (now upto a bottle of wine) she falls asleep on my bed so I leave her there and go up to our marital bed and sleep there instead.  This morning it is almost as if nothing has happened.  This time the agro turns to the weekend and arrangements for the children.

I collected daughter from school tonight.  On way home I apologise for what happened last night.  I think she heard quite a lot and makes various comments about how her mother is behaving.  Not sure if she is trying to be supportive or really feel unhappy about her mothers behaviour.  Tonight stbx is out so currently quiet but that could all change! 

It is now being cranked up an I am starting the finacial process as well.  This wil not be agreed sensible so the only to reach a conclusion is through the courts.  Sad and expensive.
