My boyfriend and I have been together for almost 2 years, and over the time I've known him I would never, ever, accuse him of cheating. He is such a lovely person and the man I know would never cheat on me. My whole family loves him and my friends do too. Recently I've had a bad gut feeling about the possibility of him cheating and long story short, I snooped on his phone.

What I found was him emailing replies on Craigslist ads of girls wanting casual sex. I've attached an example. I'm 20 and he's 23 (he's lied about his age)

Basically I want to know how to confront him about this without seeming crazy. I feel bad for invading his privacy but I need to say something. Please give me advice on how I should handle this. I'm a such a loss of what to do

I also don't know if he's acted on anything just that he's sent the emails
