This is how I find myself waiting for "Sophia Loren".
She seems rather on edge and sends me a text message at the time we're due to meet asking why I'm using the website.
Sadly, I feel I have got all I want out of our brief relationship - two cups of coffee and a short conversation - and it's time to move on and find someone new.
Many of them are middle-class, many have young children.
And all of them are looking for an opportunity to betray their spouses. But I wanted to find out what sort of woman uses such a site.
