Why would a guy ring you on no caller id after a first date?

So I went on a date with a guy. Prior to the date he use to message me a lot in an overbearing way. He was quiet during the date but we had some physical contact.

He said he’d tell me straight if he wasn’t feeling it as I asked him. However his tone has completely changed he’s messaging but not same as before.

im also sure he’s rang me on no caller id twice I wonder why 🤷🏽‍♀️ first time I didn’t hear it second time I picked up and the person cut off after a few seconds. However im sure it’s him.
