Hi i am new to this site and just wanted some advice please,i have two children with my ex one aged 13 and the other is 2,my ex has been giving me 140 pounds a month for the eldest and only this month put it up to 300 for both,he is not interested in the kids only seen his daughter 5 times in 2 and a half years and saw his son when it was convenient over the last 13 years,my son doesnt want to see him again after him threating to kill all my kids and saying he loved his dogs more than his kids to my eldest son.He is on a very good wage earning 1250 pounds a week take home my problem is when i contacted the csa they said he should be paying 250 pounds a week for his kids it annoys me when i am struggling to make ends meet and do things for the kids coz i have no money and he is living the high life with not a care in the world,i am worried about what his reaction will be if the csa contact him.should i just carry on and take wot he gives me for a quiet life or fight him for wot he should be paying.
