I Split with ex partner 6 years ago from him being aggressive and violent towards me when our baby was one years old ,his family is also aggressive towards me and especially his sister , he’s never been consistent , never payed a penny and also is still very sensitive to what I have to say , I feel I’m on egg shells to please him , because I still feel threatened by him and his family , I moved on meet new partner and have a younger baby , my daughter been coming home saying he’s saying nasty things about my partner and baby , so I asked him nicely not to talk to his daughter about her sister , and flips threatening to go mad , his then messages me saying kids of nasty things calling me every names , I don’t know how to act or what to do as I feel it brings me down
