i dont have any ex's like that then again i dont have any children, my fiance has a nightmare x who did nothing but try to blame me for everything that her children do wrong that she doesnt agree with , when me and my fiance first got together she had a vendetta against me and tried to stop him seeing his children because he was in a relationship with me etc, it was ok for her to shack up and have 2 kids by the first bloke she met though, she still has this vendetta it's been 3 years, my fiance's kids get no attention from their mother so when they play up its to get attention but me and my fiance get phone calls about how it's our fault, the oldest who is 7 turned round to her the other day and called her by her real name and their when their mum asked why she didnt call her mum she said ' you dont act like a mum so i wont call u it anymore' what a lovely threatening phone call i received, i do nothing but try to encourage them to have a good relationship with their mum but there is only so much i can do and i still get hassle
