Relationships

My boyfriend went to a party without telling me, should I worry?

For context my boyfriend is an insurance agent and will, when covid restrictions allows, go out to meet clients. He told me 2 days ago that he was meeting with a client today. I thought it was no big deal, considering his line of work. He left early afternoon and I was under the assumption that it was only going to be a few hours max. I haven't seen him all day so I am waiting up for him to come home. It's really late and he hadn't texted me and I work in the morning. I let him know I was going to head to bed soon but I would try to wait up for him. He messaged me back that he met up with some guys and they're going out to party. He waited so long to tell me that. That's not just something someone does without telling thir SO right? I know if I did that he would be upset and suspicious and say I planned it or that I might be cheating. I'm really worried and hurt he didn't tell me sooner. If he told me that he wanted to hang out with his friends, I would've been fine with it, but this feels like a slap in the face. Do I have a right to be upset and hurt? Or am I overreacting?
