How do I stop my trust issues whenever he takes long I accuses he’s with a girl?

I’m dating this guy and it’s been not long at all so whenever he takes long I don’t necessarily accuse him but my head starts to wander that he’s cheating. Is this toxic? I don’t know how to change it. If he takes a certain amount of time I always text him and say who are u with I don't know why I’m like this I don’t wanna be toxic
