Help me! Cheat??

So i met my boyfriend of 2 years online. When I started talking to him he was using a fake profile and cat fishing me. He used this fake profile for 9 months before he finally came clean and we met etc. He deleted it and worked on trust and i forgave him and fell in love with the real him.

I used his laptop the other day and looked at his photos and in his photos was a picture of a man from the internet and today in his search history was 'abs in bed'. He's 100% not gay so that isn't the issue, but i'm scared he's using a new fake profile behind my back and hence cheating on me with it.

I don't know what to do!!

I brought up the things when i found them and he basically denies them! The search 'abs in bed' he tried to twist and say that maybe i had searched it and remembered it was his laptop and felt embarrassed so i was trying to blame him.

I love him more than anything in the world and i'm scared. Please any advice will be appreciated.
