So ive known this girl Ashleigh for 10 years. She is an absolute trouble maker and thrives on causing drama, i am sure we all know someone like this. When i was pregnant 4 years ago she tried to break my partner and I up but lying saying i had a STD (proved i didnt) and said he needed a DNA test cause im a slut. She got involved with my custody battle between my ex partner and I and caused a lot of problems and even called CPS on me stating i starve my kids. When they came to my home, it was pretty evident my kids are healthy and in the words of the case manager it was a "malicious report" i never heard from CPS again. My ex and I finished our court case 2 years ago now and are civil and he has a very low opinion of her too. We live in a smallish town and everyone dislikes her. She fell pregnant to a man who was married, his wife was her best friend and flatmate. Like yeah shes a bit of shit to sum it all up. Now heres the issue, this year my daughter and her daughter are in the same class at school. It doesnt bother me all that much but she stands in the playground giving me dirty looks, follows me back to my car and had her daughter push my daughter down the steps at school today.. our kids are both 6 year old. I spoke to the teacher who said she will follow up on it but I am almost at the point i want my daughter moved into another class. She is such a bitch and I am trying to rise above it all and be the mature one but I cant stand seeing her at the school, following me back to my car, grinning and pulling faces at me and worst of all her child picking on my child to the point my little girl doesnt wanna go back to school. What do i do
