Title says it all really.
The first time I did it I discovered he'd been joining gay dating apps, "scrolling through just for the fun of it" apparently.
This time was today. We had a massive fight because recently, after a year of being together it feels like the affection is dying. He has thwarted all my advances, doesn't like to have sex unless we have a shit tonne of foreplay (for him) while I get no attention back, and he hides his face away from my kisses. Hand holding is okay and hugging but not kissing today. He asked why I was crying and I told him because of the above reasons (minus the sexual parts) and he went in a huff, slamming rolling trays and going to sit away from me.
He eventually fell asleep with his back turned to me, a lit smoke in his hand so I was putting everything away safely, putting the blanket on him, when I was putting his phone on charge I noticed a notification from his vpn- a new one I didn't know of (we have the same vpn plan). I went through his search history- I'm so at fault for this but I seen he'd started using a communication app a hell lot more than "just the 'boys' chat". He joined a new group and shared very personal details about his identity he hadn't told me- but he'd also joined a sexual RP group, had his DMs open and had single in his bio.
I don't even know what to do. I love him but if I bring this up he'll just get angry at me and ignore me until the problem is "over". I'm just so tired of him being angry, I don't know if I want to make a big deal out of nothing.
TL:DR- Went through bf's phone. BF has been RP'ing and will get angry if I bring it up as I went through his phone.
