I've watched a close friend's marriage over the years
It's like a car crash in slow motion .
He , like his father tends to be insular , depressive and morose .
Talk to him and he opens up .
She, is a bubbly person , but likes to be out with her friends most evenings , weekends and holidays .
They don't share the same interests or ideas and are constantly at war with each other.
They also complain about each other all the time .
Their daughters have been affected by the perpetual disagreements .
As they hurtle towards retirement - I wonder if they'll both live in the same house with the same resentment towards each other .
I wonder if it's been a similar situation with your parents .
I also wonder about dementia - anger and aggression can be a sign .
My advice is to visit and support your father and to confide in a health professional .
I went through a similar situation with my parents .
