This is a very complicated story but following their dad moving out 4 months ago eldest child (10) has been massively struggling with angry outbursts, not wanting to leave the house or go to school (not everyday say perhaps 2 times a week)
For example - if we are to go out sometimes they have a 'moment' (so examples were into town, bowling with their friend etc) they refuse to go and argue about it beforehand, refuse get dressed and have to be talked into it, refuses to leave the house - have had to literally take by the hand, refuses to get in the car, they have also run off once outside before. It honestly can take me 20 mins stood outside with the other children already in the car to coax child to get in to go out. Once in the car they will curse (never said bad words before the break up), say how much they hate me, hate life, don't want to go to this stupid thing etc. It's really wearing me down, it's ruining family days out and annoying the other children.
Again at school they won't go to class, I have to get their teacher and on occasion the headteacher has been involved to physically take them off me as they physically cling on.
Bedtime is also a problem with them having an outburst most bedtimes and wanting to stay downstairs, also
Getting angry and physical with middle sibling - to the point middle easygoing sibling has been really upset and in tears. They were close before this.
Speaking to child after they have these outbursts they apologise, say they don't mean what they say, just are so angry and don't know how to deal with it. We talk things through and seem to get somewhere but then it's back to it.
I am at a loss of what to do, their dads in denial, doesn't act like this with him, thinks I am lying.
Child has spoken to a friend of mine and my brother and parents about everything so has lots of adults apart from me to turn too but they are struggling a lot.
