So I have been dating this guy since May. Things have been going really well up until now.

I woke up and went to check on my phone and in my sleepiness I accidently grabbed his. Normally when I try to unlock his phone it has a passcode that I do not know what the pin number is. So his phone opened and there is was.

He had been chatting back and forth with a girl on Google Hangouts. I know I should have just turned it off and ignored it but it got the better of me. So I read the conversation.

The conversation I read wasn't too bad. It mostly just sounded like some girl trying to get attention and him rarely responding. Except for sending pictures of the new puppy he had adopted.

But since I had his phone unlocked I was curious to who else he had been chatting with. So I found in another google hangout message he had been chatting with some girl who confessed her feelings for him in the beginning of August. He never responded with how he felt back. She had messaged him a very sexual message and he had responded to it...there I found a picture and a video of him jacking off and a picture of her vagina. I was stunned. Especially because I told him that I absolutely did not want him sending nudes to other women. (He had asked if he could post nudes on Reddit on day).

Since seeing that message I could not stop looking. I found tinder, okcupid, and POF installed on his phone. The okcupid account and POF had no messages but the tinder account had one message.

I think I'm in shock. So now I'm venting, chain smoking while listening to him snore, and debating on just sleeping on the couch. I want to talk to him about it but I'm terrified on how he will react to me snooping on his phone...any advice on how I should proceed?
