Help ! It's my step sons birthday party tomorrow, his mum has been a nightmare prior and now it's got worse. She demanded that my husband drive 2 hours to pick up his bday cake (which we paid for) and when he refused, due to it being in working hours - she told him he had ruined his son's birthday ..... and not to come !! Is this normal spiteful behaviour or do we have an idiot on our hands ??
