Someone please tell me if I'm being crazy. My boyfriend who I've been dating for almost two years suddenly started muting and deafening himself on discord at night for about 15-20 minutes every few nights.

He used to suffer from a porn addiction and it caused a ton of problems in our relationship. He agreed that he wouldn't watch it anymore and that said he didn't WANT to watch it anymore. I believe he's doing this so he can watch porn and jerk off, then come back and act like he was just afk for a bit. 

This last time I asked him what he was up to he said he was eating and watching youtube vids. This is something he has ALWAYS done, but he's never muted and deafened himself while doing it. It's just very odd and my intuition is telling me he's lying to me and watching porn. The fact that he's doing it later at night, the fact that he's not just muting himself but deafening himself to, the amount of time he's doing it for.

I'm fully open to the idea that' i'm being ridiculous though, just voicing my thoughts.
