I am a current NQT in my first term at a secondary school. I have grown close to a teacher in my department and he has been a real support to me, though he is not my actual mentor. He has made it clear he’d like to start a relationship with me. How bad an idea is this? I should probably also say he is older than me, and married with kids though he says he is currently separating from his wife. Could this affect my career?
