Why do I always worry 😩

So my BF told me he was on his way home. Should have taken 45 minutes now it's been an hour and a half?!? Hasn't answered a text or said he was going to be later. So either he's hurt or something else. It's not like this is the first time but I don't think he realizes how much I worry about him. Like what the heck is he doing?? :/
