DD (12) has had trouble with this other girl last few weeks of primary (we are in Scotland) including being hit & pushed. No apparent reason. Two incidents at parties during hols, again pushed & DD pushed her back first time. Few mean comments made but DD has just ignored. Then yesterday on way home from school she pushed DD out onto main road, DD spoke up, she then grabbed her so DD pushed her away & ended up scratching her, DD actually apologised but girl went mad calling her F**g C etc. DD just then walked away. This girl is Miss Popular in their group which has expanded since end of P7. One of DDs friends has called her up on the meanness but rest have said they know it's mean but they want to stay friends with this girl ie they are too scared of her to take sides. DD is now also being excluded from things outside school. My fear is (which is keeping me awake) losing her friends, her support system, just when she needs them. We just told our kids a few weeks ago we are separating. What would you do?
