'its a choice between me and your (precious) daughter and that I need to make her (my GF) my priority.
My Gf, has continually wanted me to sever my own life to build one family and wanted me to change my children's school to the school her children went to. I do know my GF IS at her wits end - she doesn't deal with stress well, but when she feels I defend my daughter it's met with anger.
If those are some posters' ideas on responsible parenting, then their notions differ very much from mine. Destabilise the children after they've had so much change already, to her children's old school? Why? Demand a parent prioritise a partner over their child? Set that up as a choice between them?
Your child may have issues and may need help, but from what you've said about the two partners you have chosen, I think you may need the Freedom Programme. They both sound controlling and angry people, and your children need stability and consistency.
And there's absolutely nothing wrong with explaining why something is being asked of a child, as long as they still have to comply. I have no truck with the idea that you can treat a child with contempt and expect good behaviour back. Courtesy needs to be modelled as well as taught, and obviously you need to be in charge but there's no need not to explain your reasoning so they know it's not arbitrary.
You need limits, boundaries and routines with kids, I think. If your daughter is pushing them then you need to be firm. But she also sounds like she needs reassurance, and with the women in your life, I'm not surprised.
I dont understand people having sympathy for the GF who scapegoats a child and demands the father of the child choose between them. No matter how bratty the child may be, no reasonable, concerned adult blames their current dissatisfactions on a child whose life so far has been filled with separation, divorce visitation to an unstable household and family size doubling. It seems like as soon as the girl felt secure enough to push boundaries, this GF reacted badly. Sooner or later, each of those 4 children is going to go through a bad phase, if the GF cant cope any better than this, good riddance.
Absolutely agree.
