should i ask? a chat between My husband and his Best friend.

This weekend My son (2m) and i we’re at my parents place. One hour away from our Home, than we shared with My husband. The plan was kiddo and mom go to grandparents place, and dad and Best friend’s (we call him A) stay at our house for the weekend. A was in the city for medical appointments. A is also My husband business partner. Today, monday, after wey return Home, i’m going to check on the cameras (i wfh) how my son is going and the cameras are off. All of them. It’s seems weird to me, well, i starts the cameras again and could hear a chat between My husband and A (whom are clearly wasted at 4 am). Husband: “hey, i was thinking we should call B and C (another male friends) and then go to…You know, look for a little bit of fun” then he stopped himself and cut off the cameras with his phone. Today i asked him if he disconnected the cameras and the answer was no, love, surely was the internet. what the fuck? What the fuck? I would never think he will deceive but…this is weird as fuck. He works from Home too and we spend day and night together, always, except when im going to My parents place. How do i ever approach this? What the hell do i do? Marriage is good. It changed a lot after the birth of our son but is still good. There is love. I hace known this man for twenty years and now this? Sorry for any mistakes, English is not My first language.
