My 4 yr old sons behaviour is causing me a lot of anguish. His mum and I had a very acrimonious split over 2 years ago but I have always had 50-50 (probably more) access/shared parenting. Sometimes mum takes advantage but I never refuse I just love having him with me. I am in a stable relationship of a just over a year - she also has/had a new partner but they split up every few weeks (the last time just a couple of weeks ago). My son told me a lot of stuff last week-end which prompted me to talk to his mum. She admitted that things had been volatile and my son had been affected by this. Yesterday he told me more stuff that is worrying me - saying things like mummy's house is an angry house I want to live with you daddy. TheN this morning he didnt want to go to nursery and threw a tantrum, kicking, lashing out then starts asking for his mummy and saying my house is angry. He also says that he wants to be a good boy but his brain is angry?? He is such a lovely chatty little boy usually but I am seeing the personality being sucked out of him and I dont know what to do. His mum is very aggressive and a hothead and it's always someones elses fault she has a lot of issues relating to her childhood. She also has an older boy (19) who has left home and wants no contact with her - he also was an angry little boy/young man. At nursery and pre-school they have nothing but praise for my son saying he is a joy and such a good boy? I am going to speak with my ex this evening any advice/help/suggestions would be appreciated as I feel so alone and out of my depth. I am going to suggest to her that my son stays with me for a period until she sorts her personal life out - good idea or not? I just don't want to go storming in with the stuff he's told me in case he is playing us off against one another - but neither can I ignore it - HELP
