Oh, where to start...
DH and I have been together for six years. He ex wife left him three years prior to that.
My step son and daughter are now 13 and 17 respectively. It is very obvious the son is favoured at home.
Three years ago we took DSC on holiday with us, including my own children. We discovered DSD was making herself sick after eating and had been cutting hersel falso. Her Mum knew about the cutting herself, but not about the bulimia. DH and I chatted to DSD when we got home and she told us her Mum had been weighing her and had tried to join her to a gym, and also told her if she ate less she would lose her 'tummy'. Comments had also been made by her Mum's boyfriend (who is married, and they know he is married) about her eating habits/how she holds her cutlery etc. She had actually been told she ate like a pig.
Roll on a few years and the ex wife recently found out that DSD had been to the family planning clinic, she went mad. Now DSD has been putting herself on porn sites and going on webcam to men 'doing things' to herself. She has also been seeing several boys. She knew her Mum would know about the porn/webcam thing as her Mum put a programme on DSD's computer which would monitor her online activities and she knew about this and her Mum would check it.
On top of that, DSD had her car 'confiscated' for what her Mum deemed as bad behaviour, and is still regularly grounded. (I really feel that if you're old enough to drive a car, you're too old to have it 'confiscated' or be grounded really) Recently, upon being let out, DSD went to a prty and then disappeared with a boy/man she didn't know for several hours, lied about where she had been, and the asumption is she went off to have sex with this lad she didn't know.
The married boyfriend went to Australia with his wife and children last year, and then came back and took the holiday DVD round to show ex wife and DSC, which I find a bit controlling and odd. Als, when hubby visited yesterday he noticed a new notebook laptop and asked the children if it was one of their christmas presents. DSS replied it was for 'married boyfriends (although he used the name) wife. I really don't think knowing abotu sucha relationship and how their Mum is being treated is helping them. (She has been seeing this man at least since DH and I got together, wants him to leave his wife, but clearly he isn't going to)
There are a few problems with DSS, but not on the scale of DSD. There have been other problems as well, but I don't want to go on too much and can't list everything, these are the main things. I am very worried, for DSD particularly. DH is sadly useless at sorting things out, and the ex wife refuses to meet me or speak to me, so I feel helpless. I have considered social services, but not sure if they'd do anything due to DSD's age.
