I am a step mum to two boys 12/14 since they were 3/5 the eldest is so disrespectful and nasty to me and it’s all my fault never his, his dad has spoken to him but then he threatens to not come down or says his dad is taking my dude and is scared of me, it is now causing Hugh problems and my husband is concerned they will not come down I also feel like they gang up on me I do a lot for them and feel angry and hate them coming down. The boys mum had always been awful to me and never wanted to meet me and I have tried to meet her as I felt it was important. I know I should step back and let their dad deal with it but I find it hard when they are in my home. I don’t ado fit much off them just to be respectful and polite to me. It is making me ill now and don’t know how much more I can take, any advise would be great
