'Will I lose my teaching job because I had sex with one of my pupils?'

Exchange here. Excerpt:

'Dear Miriam,

I'm a 27-year-old married woman and a teacher. Last month, I had a one-night stand with a pupil. He's 18 and very mature for his age.
...
Now I hear there are rumours circulating around the school about us and I'm having kittens the head teacher will get wind of it. What can I do?
Erin

Dear Erin,
This is a serious breach of professional ethics as well as a betrayal of your husband, which is likely to have serious consequences for you.

Your drunken sex romp may well have sabotaged your professional future and your marriage. It seems likely you're living on borrowed time. Clearly, the boy has bragged to someone and it may only be a matter of time before the gossip spreads uncontrollably.'
