Am I crazy?

So I've been with my boyfriend since 2016, & last year or so (I don't really remember..) he called me in the middle of the night blowing up my phone waking me up.. He just kept saying over & over that he "messed up" so I was like wtf.

I guess he had downloaded Grindr again when he was drunk (he's bi I guess) & started talking to this guy. But little did he know, the guy knew me & he was from the same town as me. So the guy messaged me, to tell me my mans "unfaithful" but my boyfriend got on my Facebook account & deleted the message when I was sleeping. & blocked him. Still to this day I don't know what the message said.

My boyfriend was very regretful & he was crying & felt really bad. & he made is VERY clear he'd never do such a thing again, I've forgave him. Because I know he'd never actually do something with someone else. Ever sense then I'm a little insecure, & when he's asleep every so often I try to look through his phone 😔 I was never like this before.

But since that incident happened I get super nervous with what he does on his phone.. I never find anything though.. But then my anxiety tells me "well he probably deleted it before you could see". I don't bring it up, because I trust him more than anything. & I don't want to start arguments over something that might not even be there.

It's just something that ALWAYS low key eats away at me. & I have slight trust issues with him now in the back of my head.
