Calling all the toxicas…

So I know my husband is cheating on me. However he’s super discreet and managed to hide it perfectly. He doesn’t know that I know but I need physical evidence, right now he’s living with his mother to take care of her temporarily which gives him the perfect liberty and not having to hide his phone. We have a phone plan together but I can’t see who he’s texting on iMessage only through text. But I KNOW he’s texting her, I know her number too. Is there anyway to see his iMessage texts without him knowing? Do you guys know like a reliable hacker or something? I have his iCloud info but I don’t want to log in and then have him be notified.

The reason I NEED evidence is for legal evidence and other family things that are farther complicated. We have to many assets together. I already know it’s going to get messy. HELP y’all
