Found My Husband's "Fishing Trip" Photos. He Wasn't Holding A Damn Fish

So I'm doing the thing where you back up your husband's phone to the cloud because he "lost photos" before and cried about losing pictures of our dog. Sweet right. I'm a saint. Anyway I'm scrolling through to make sure the transfer worked and I get to October. He told me he went to the Reservoir with his cousin for a weekend fishing trip. Came home sunburnt and grumpy and smelling like Bud Light. Normal behavior for him. Except the photos from that weekend? Not the Reservoir. Not Ross Barnett. It's a goddamn Airbnb. I can see the same blue throw pillow in like 14 pictures. And in three of them there's a woman's hand. Just a hand. With a ring on the thumb and one of those stupid little tattoos that looks like she did it herself in 8th grade. A lightning bolt. On her wrist. We've been married six years. Bought our house in Belhaven last spring. I made him a charcuterie board for our anniversary in March and he cried. CRIED. Meanwhile he's been "fishing" once a month since like June. I started cross checking. The weekend he supposedly went to Tunica with the boys? Same blue pillow. The "work conference" in Hattiesburg? Different Airbnb, same lightning bolt wrist holding a margarita at what looks like Babalu. He took her to Babalu. Where we had our second date. I want to set something on fire. I haven't said anything yet. He's downstairs right now watching the Saints game eating the queso I made him. From scratch. Like an idiot. I keep thinking I should drive to her place, I think I know who she is, there's a girl from his gym with that tattoo, and just knock on the door. Or do I let him keep eating the queso while I call a lawyer Monday morning. Tell me what you'd do because I am LOSING it.
