Please can anyone offer advice? My ex is saying he can't afford to pay the amount of CM that the calculator suggests. I don't know how much is due to the fact he is renting a nice flat so they children have a nice second home or because he's bad at budgeting. Either way, I feel I have no choice but to let him reduce his payments because I don't want my girls to have to suffer by losing their second home which they really love. Im just not sure how to go about suggesting a fair amount? Ultimately, he'll probably say he can only afford x and I'll have to accept it but just wondering if anyone has been in a similar situation? I'm not earning loads but have been managing the last year just about despite getting next to nothing in terms of CM. Maybe I should just let him pay what he can afford if I think I can manage and take the more peaceful option? He doesn't seem to understand that he has an obligation to pay, and the fact that I work part time at the moment (one child still not school age) probably annoys him. I would look for more hours if I need to, of course, but don't want to lose that time with my child just because he can't sort himself out and budget properly, if that is the case here.
