Am I overreacting?

So, I will make this as short as possible.

My husband has been doing some fishy shit lately. He has been going outside ALOT lately. Like, a lot. He’s been telling me he’s gonna go outside and smoke and he’ll be gone for an hour. It does NOT take an hour to smoke. Well tonight, he told me he was going to take the trash out and he came back inside over an hour later.... When he got inside, he fell asleep. And then he got a phone call from some guy and then the guy texts him after he calls and says, “I’m outside. Wya?” Obviously I saw this because he left his phone next to him on the bed and he was sleeping and when I saw someone was calling him, I couldn’t help but see that he texted him afterwards. Well 5 minutes later, he texts him again saying that he needed to talk to him ASAP and it was an emergency. So that’s the first thing that happened. Yesterday, on Thanksgiving, he went outside to talk to his friend on the phone about Fortnite. We were at my grandmas and he was outside for 45 minutes. The only person he contacted yesterday was a chick that he used to work with. He FaceTimed her for 45 minutes then came back inside and straight up lied to my face about it. I haven’t talked to him much after I asked him why he goes outside so much and why he’s always out there for so long. He got a HUGE attitude with me saying I shouldn’t be questioning him and I should trust. Do I need to get over myself and stop being pissed about it? Or do I have a right to be mad?
