ExP can't afford to put any money into an account for our DC, he rents a big house that eats money and says he needs the money to pay his gas and electric. He has the DC Saturday afternoon - Sunday afternoon every week.
I have lasted without his help for 13 months and to be honest I don't need his money but DD starts school next year and they will start becoming more expensive soon. I've spoken to the CMO or whatever they are called and they say that i can claim but they determine the amount so I can't ask for say, £100 a month.
We are usually amicable but are having a huge fall out at the moment because he makes no effort with the DC, I drop them off at his, I pick them up and he does nothing with them. He forgot to pack an important medicine in the bag when I picked them up last night and refuses to bring it back to me because he doesn't drive and lives a whole 2 miles away 
I'm getting a bit fed up of having to do all the legwork and having him constantly calling me names - wankmother this morning?? For no reason and I'm wondering whether I should just make a claim regardless of his ability to afford it?
He could move into a house that we own together but can't sell due to negative equity and save about £500 a month (we rent it out) but he won't because it doesn't have a garden.
