I posted before about my driving instructor's inappropriate behaviour. He has commented on my bra, sniffed my hair, leaned over me into the footwell and touched my leg, leaned over me repeatedly to adjust the windscreen wipers when I asked him not to amongst other things.
I ended up recording him as it was so bad, but did nothing with it. I ended up cancelling lessons as I couldn't bear to be in the car with him. Then I told him on the phone that I didn't want to continue lessons and why. He went absolutely ballistic at me, calling me all sorts and I think I'm all that. Then he rang my dp who took his side. He was furious and threatened to come to my house, so I threatened police. He then went to our local pub and slagged me off to all our mutual friends, calling me a liar and the rest of it.
I don't know what to do. I could report him to the regulating body but won't get the money back I paid upfront (only used 30% of what I paid). Could take him to small claims. Could report him to police. I'm actually scared of going into our small town in case I run into him or someone he's told. I'm now a pariah in our town 
Dp has been unsupported. Think he thinks it wasn't 'bad enough' and I shouldn't rock the boat. I suffer from anxiety anyway and I'm just a mess. What should I do?
