Dad refuses to pay towards chldren

4 years agon i was left to care for 3 young children when their dad walked out. since then i have not recieved a penny towards their up keep, apart from one time last year when he contributed £35 towards my sons weekend school trip away. Im currnetly just recieving money from child benefit as i returned to work last year – to try and better my childrens life – however in December i had to return to being a full time mother due to not earning enough.

My oldest is now 11 and with him starting secondary school back in september i had to cover the full cost of his uniform (around £120) it frustrates me as he seems to have no intention of getting a job or paying anything. When i was in touch with the csa a couple of years ago they spoke to him and came back to me with that he cant afford anything.

He has regular contact once a week and am finding it a struggle and often think should i just end the contact all together but i dont want to hurt mychildrens feelings, but not sure what else to do!!!!!!
