It could've gone either way: he could've stepped in and give you a night to remember or he did a runner because he wasn't expecting such aggressive sexual predations from a woman he'd just met. to be fair i'd do the same, maybe not bolt but ask what you were doing and feel awkward. it's nothing personal.
Some years ago over 20 to be precise i opened the door naked to a guy i met on the train coming home from work we chatted and he asked me out so came over to pick me up. I opened the door naked and he couldnt handle it and run off. The stick i took from my mates over that.
