What a creep!

Get the reference then cut all ties after a new employer follows it up. Even thanking him when you get a new job could lead him to think you want to stay in touch.

I'll never get involved with someone at work again, not that I've had a job in five years. Stupid to realise it would end in any other way than it actually did. Thought he was a decent guy but fell for the oldest line in the book!!
