My cousin and her hubby won about 2.4m not too long ago.
They gave about 25k each to parents and brothers and sisters etc (nothing to cousins :o( )
Its caused a great deal of problems!
My cousin is an identical twin her sister has become really upset by everything and how her sisters changed.
They've grown up together as best friends but they hardly see each other now.
My cousin that won is also extremely unhappy in her marriage but due to this big win and all other attachments (child, house etc) i dont think she'll leave him, even though her parents and sister wish she would.
They're in th eprocess of buying a house for about 300k and they also bought two cars.
