I have a friend whose wife died after a fairly protracted battle with cancer. He was youngish, with their child to look after. Within a few months, he was seeing another woman. His wifes friends were horrified (and I was a bit shocked too), but honestly, I think he just wanted a bit of normality, and yes, probably sex, given it had been off the cards in his marriage for quite a while.
I don't think it ever really became a 'relationship' and it fizzled out. I think the poor bloke was floundering. He needed someone.
After another couple of years, he had a girlfriend, who he has just married, 10 years after his wife's death.
Our Welfare State. Is it broken?
