Did my husband cheat??

I noticed my husband took screenshots of a convo between him and some lady. It must be a sex worker because she gave him rates and he kept asking for pictures…idk if he got any but the same day the screenshots where taken his locations in his phone put him in her area for about 30 minutes. I asked him about it all and he said he doesn’t know how those screenshots got there and if his phone said he was in that area it’s because he had to drop a friend off for another friend and I feel like that’s the same night he came home and went straight to the shower. He goes to a car buddies home and they work on cars and stuff and smoke a lot and whenever he comes home he usually takes a shower as he smells of smoke so I didn’t think anything of it but now I’m really worried. I think he cheated. It may not even be the first time.
