How should I confront my husband who I suspect is cheating?

I’d like some advice on how I should confront him. Nothing dramatic or over the top.

Just some background info - married for 7 years, have 2 boys together. He has been the most amazing husband to me so far, no red flags. Caring, loving, understanding. But yesterday I went on his Google account out of boredom and went on his history. For months now, he has been visiting Snapchat and I presume deleting it after every use. I also saw he visited some dating/chat apps in his history. When I checked the time and date of these events, it’s always been late at night (he drives Uber some nights), or when I’m at my moms. I’m quite sure he’s up to no good, If not physically cheating, at least going on these apps behind my back.

I have taken photos of everytime he’s visited these apps. So my questions is - how do I confront him? How can I make sure he doesn’t come up with some excuse?

Please keep in mind he has been such a wonderful husband so far, so I think I’m in denial a little. Any advice on how to approach this?
