...or if it's just a tricky situation that can't be resolved. I'll try and be brief. Parents of two children break up very amicably when children are very young. Both remarry. Children live predominantly with mum and become family unit with new dad and half sibling. Dad and new wife don't have any more children, enjoy nice holidays and focus on work and hobbies. Dad sees children when it suits. Then Mum breaks up with new partner. Children are now teenagers. Mum wants dad to help more with children now she's single again and gets very angry when he can't because of work commitments (freelance so not 9-5). Basically mum now wants dad to look after children every other weekend and when he can't she thinks it's his responsibility to find someone else to look after them. Her mother helps out a lot with looking after the children but their dad's mother is not so keen to help out, she prefers to see children when it suits her not have them thrust on her. She is basically very angry about always being asked to look after her grandchildren when her son can't and bending my ear off about how unreasonable the mum is being trying to palm her kids off every other weekend. Dad is getting very stressed about this but stuck between a rock and a hard place. Just curious what others think and if anyone has had a similar situation and how it can be resolved.
