Sure, what you have just described feels stressful just to read.
I think you did what many of us would have done by feeling your fear and facing him and shouting at him. It is no surprise that he scuttled off. He had to scuttle off, he will be doing this a lot now the police have his number. What you did was brave and rash and shows that you are feeling angry.
OF course he is going to say you are lying- the alternative is to admit what he has done which he is never going to to do. He will only ever be FOUND guilty, he will never admit guilt.
What you have been through this weekend is huge. It is scary and it is understandable that you now feel very vulnerable and a bit lost. Any of us that had been through this would be feeling the way you are.
I suspect that he will leave you alone now, he wont want any more police sniffing around.
You can be free of him now. And it will take a while for all of this to sink in. And your bodily reactiom (panic) is entirely undestandable for what you are coping with. YOu are in "fight and flight " and at the moment are still dealing with both wanting to square up to him (how brave you were) and get away from him. Hence your body acting in the way it is.
Right now though, what matters is:
Can you get through tonight?
Tomorrow?
Sure, you are AMAZING.
