I have met and become friendly with a woman at children new school. She is really nice and we seem to be forming a friendship.
I was invited to her house for a coffee and play date for the kids. Her husband was there, we realized we grew up in the same area (though I left a long time ago, him more recently)
When I said exactly where I grew up "Oh, the snobby part"
He was saying how much he like where he lived now as there" weren't as many really offensive and racist word now". When I said "I hadn't heard that expression in forever, thank goodness" He said " Oh you really are a snob then" 
He really is a twat.
Problem is she wants to start getting together more often with everyone. I would like to keep it just us.
How do I keep putting her off without offending her ?
