He's a control freak.
If you stay, he will end up traumatising you both emotionally and physically.
Get out as soon as you can. Leave your key and a note of goodbye: give the reason but phrase it politely.
Do it when he's not there.
Ensure that he cannot find you. That will probably mean changing your phone number. Tell your friends and relatives what's happening to ensure that they don't pass on your new address or contact details.
In future, on any first date learn to look out for the tell-tale signs of a control freak. If you see them, don't give personal contact details and don't agree to a second date.
If in doubt, look up the signs on blogs at Psychology Today.
