So it seems Beth and I have a mutual friend! I got chatting with said friend and I can confirm she did indeed marry her history teacher (not sure if he actually taught her) but he taught at Didcot girls school where she was a student

She lived in a very rough area and the posh voice is a total act to fit in and be cool. She was just as stuck up in school as she is now! My source also informed me that her mother is somewhat of a party animal and has got about the town quite a bit but has now settled down with a toy boy
obviously big age gaps run in the family!
