Urgent what should I do?

Anonymous
I just found out my husband had the strippers number from his friends bachelor party saved in his phone.. when I first saw the saved number a couple days ago he explained that she was dropping off cocaine that night, he never even saw her and that the boys did the pick up when she got to the hotel. We moved on from it that day because I didn't have a problem with the drugs as it was a bachelor party.

Today, I had a horrible gut feeling that he was lying because he has been acting so guilty since so I looked at the bachelor group they made to talk about their plans and her stripping advertisement photo was on it. (I found out what she looked like through her whatsapp pic from his phone because she's still saved). He has also contacted her on multiple occasions since the bachelor party. His excuse for those times is he spoke to her boyfriend about a marijuana prescription he wanted to get.

Now I know snooping is wrong but I'm 5 months pregnant, if my husband did something with this girl after the bachelor party, I'd want to know so I can see how I want to proceed with the relationship. Please don't tell me I invaded privacy because he has clearly lied and now broken my trust so I don't see what I did as wrong. I feel like I found something valid to be angry about.

He's now asleep next to me it's 5am and I just want to slap him awake and yell.. what should I do? Do I lose it at him or stay calm?
