My abusive ex has reared his head....Again

I hadn't spoken to him for 4 months.

He emails (he's blocked from txts and calls) saying he loves me and wants another chance and knows we can make each other happy. I reply saying i don't love him and he needs to stop contacting me. A few weeks pass and he emails again so i ask him why he's doing this and he said he just wants another chance. I replied telling him I'm seeing someone​ and now and please move on with your life.

He totally flipped.

He always thought i was cheating but i never did.

He has been sending me email after email full of total hatred.

Here are a few quotes;
You honestly repulse me. The 1st thing I'm doing Tuesday is getting myself an STI check, **** knows where you've been

You've got until Friday for my stuff to get back to me. If it's not, your scummy, infected sex toys that are still at mine will be dropped outside your front door

You even had the cheek to say i was being possessive, when really that was just an excuse so u could.do your normal thing of juggling 2 cocks.

You've got til Friday for my stuff to come back

He wants the gifts he gave me back. When we broke up he told me to throw them away which i did. My main worry is that he's said if i don't give them back he will come to my door.

I told him if he contacts me again I'm calling the police. He replied saying if i do that he will contact my ex husband and tell him what a slut o am.

I've called the police and going to the station tmw to give a statement.

I've been seeing a new guy for a few weeks, should i tell him what's going on??

I'm terrified of him please help
