My son's 5 and his dad and i have been apart since he was 1. He pays £45 a week for maintainence but often misses payments because he has 'other commitments'. He doesnt he lives at home with his mum and only has to pay for his car. He works full time and makes an ok wage. Our son has special needs and he walks on his tip toes. Because of this he wears out shoes really easily, scuffing and making holes in them so I'm buying shoes every 6 weeks as i dont want him to look scruffy. I asked his dad yesterday if he could buy him a pair of school shoes he said absolutely no way i already pay child maintenance. Baring in mind he's never paid for any shoes/clothes/school uniform/nursery fees/school trips or anything for that matter! AIBU to ask him to pay for a pair of shoes even though he pays me £45 a week (most of the time)?
