Sure
You are not making a fuss over nothing, and you are not a drama queen. Over the last few weeks you have had dozens of Mumsnetters read your account of his behaviour and they have all agreed, to a [wo]man, that his behaviour is at worst, scarily abusive, and at best, unacceptable harassment.
I have never been in a situation like this, so i dont know what else to say. If you can force yourself, I would be inclined to try to speak to someone in the police again, ask what is being done, why it seems like they are downgrading it to just a "talk" when you were told he would be arrested, and go from there.
I do still think that police need to speak to him [at the very least] to make him realise that you are very serious about him not contacting you again. And he IS harassing you, no doubt about it.
Good to read that your tutor is supportive.
And yes, the vrooming around on the motorbike is fun....technically i can continue to do this on L plates with just the CBT certificate for two years before i would need to redo the CBT, but i want that bike licence, just to prove to myself that i can do something that i never thought I would
