Fine. I didn't express myself brilliantly last night. However, I have now refined the question and the point, so let me assure everyone that I was put off by the sudden departure and the confusing quick peck followed by a somewhat enthusiastic text.
Wait and see if he contacts you again. I have a feeling he won't.
You don't need to have a flashing sign on your head saying Desperate for sex for guys to pick up the message.
For whatever reason, he wanted to leave. Did he say why or where he was off to? If he didn't, then that to me says it was not genuine.
Most people would say at the start of the date, or even during it,
'Look I'm really sorry but I double-booked myself tonight, before you and I met, and I've got something [fills in blanks] to go to. Let's get together next week again?'
Suddenly disappearing to some unknown event doesn't sound great.
Just be glad he didn't shag you and then ghost you which is another less nice option.
And decide if you want ONS, or a Fuckbuddy, or a relationship if you are dating again.
