<human>: Provide a brief overview of the text.

Disclaimer: I did look at his phone to verify, and the evidence was all there. 

We both broke our respective promises. Mine to not look at his phone if I didn't trust him, and his to not view porn while I stay the night. 

I'm not sure how to handle this. It bothers me A LOT and we've had arguments about this issue.

I tried to nip it in the bud by asking him to come to sleep at the same time as me, but he will spend upwards of an hour in the bathroom before coming to bed. He always says he's reading things. And when I check his phone, I see that he's lied and has looked at a range of things. 

The entire situation makes me really uncomfortable, and I suppose I'm looking for perspective and sound advice.
<bot>: My [26F] boyfriend [28M] of one year looks at porn when I stay the night, even though I asked him not to and he promised he wouldn't. I found out because I looked through his phone.
