Ds is 12 and his maintenance has never changed. I pay for everything and his father pays £200 a month. I don't know how much he earns but, from what he's said, he can work for a week and have enough maintenance for 3 months. He has another family now and a 3 year old, he doesn't live in the UK as he moved when ds was 3. He doesn't pay towards ds's trips or extra curricular activities. I have asked him if he can increase the amount he pays but he ignores me. As ds grows his clothes/shoes become more and more expensive. His school shoes were £56 as they need to be sturdy due to a problem with his ankles. He's going on a school trip on Wednesday which leaves school at 07:30. The only way I can get him there on time is if we stay in a hotel overnight as the school is 20 miles away. I pay all of his school fees and buy his uniform. He did contribute £40 towards this 2 years ago which paid for not a lot. Should I just put up with this? He doesn't see ds. He'll visit once a year, sometimes less and will see ds for an hour when he feels like it. He will just call to say he's here and expects us to drop everything so that he can see ds (for an hour). He rarely calls ds, doesn't send letters or emails even though I've asked him to. He's keen for ds to fly over to see him, yet says he has no time for him. He's also useless with children as he has no patience. He ended up telling ds to 'fuck off' the last time he was here. WWYD? If I go back to the CSA will ds get less?
