Found suspicious apps?

I found some suspicious apps on my husbands phone like “Burner” and “second phone number” is he cheating? It was in his download history on the App Store. He’s talked to girls online before and we went to counseling over it. I had a sneaking feeling and o asked him but he denied anything so I did some digging and found 3 second phone apps as well as the “Line” app.

Update: I confronted him about it but he says it’s been forever since he downloaded those. That makes no sense because there were apps he downloaded before that places them 3 months ago, not years like he’s saying. The previously downloaded apps go in order from recent to past.
