Where is my husband?

So about 3 hours ago my husband walked outside with no shirt or shoes to our balcony claiming he was going to smoke a cigarette. The balcony is right outside the front door and has a stairs connected that takes you down stairs towards the parking lot. He went outside with no shirt or shoes on and left his phone behind. When he went outside I went and took a shower and when I came back I peeked my head outside the door to see what he was doing and he was gone. Cigaraettes were on the patio but he wasn't. He has done this once before and claimed he was downstairs talking to the neighbors but they're old men and I doubt they have that much to talk about. I went downstairs to see if he was there and he isn't. So I have no idea where the hell he is or what he's doing and I'm highly sketched out and suspicious considering he walked out with no shirt or shoes or phone. I'm so nervous he's having an affair with someone in this block and that's where he is. What do I do? I'm freaking out.
