my oh has offered money to his ex partner who he has two children with, and she refused it, it was only £20 a fortnight but its all we have at the moment, we dont work, and we have a baby here to feed and look after too, they get birthdays and christmas' , they got £1000 (£500 each) at christmas last year, £120 each for there birthdays this year.......
bare in mind (even though we are a couple and the money is 'ours', he hasnt bought our son anything !! , i'm the one who is always buying and thinking to buy our son stuff, today for example, he grudged me spending 99p on a packet of baby wipes as they were pampers and thats what i use, but because there were cheap ones on sale (2 for 99p) he wasnt happy and stormed away...........
so at times i grudge what he has gave the other two girls bcos he never hesitates to think to buy them anything and its always the best of stuff and he moans and grudges when i buy our son things ......
but yes i do think they should be helping and paying costs towards the kids and u have a right to go to the csa about it if ure struggling and he isnt willing to help you
