Why would he say that?

[Anonymous]

Guy I’m seeing (not my boyfriend), i met up With him. when he was driving, I was playing a game on my phone for a bit and he said he’s gonna confiscate my phone from me. He then proceeded to put his hands on my screen and mess up the game I was playing and tried to grab it out my hand.

Because you aren't paying any attention to him and being rude.

because you are not giving him your attention exactly as he wants and is comfortable exerting his control over you.
That doesn't sound safe
