My mans watching porn behind my back.

So just had a hunch and my hubby is watching porn and he knows how I feel about. I honestly think it is some form of cheating as he’s jerking off to another woman other than me but if you think I’m being ridiculous please keep your opinions to yourself this isn’t the place for that right now. But It makes me feel like shit when he does this. I give him more than enough attention too we have sex at LEAST 8x a week 😪 unless I’m on my period and he always seems to watching it when I’m up cleaning after his ass and making his lunch for him late at night. I kinda want to kill him with kindness though so any ideas? Thanks gals ❤️
