Please tell me I’m not crazy, is this how a man would act when guilty…

We been fighting bad the last month, his libido has dropped off out of nowhere, I could have swore I could smell sex on him other day right before I gave head and he jumped up and went to bathroom told me he had to pee but really went in there to clean his dick…the weird thing to me was how he did it without telling me that’s what he was doing…and he’s a very clean person always showering so it’s not common for him to have a smell…also he’s been accusing me like crazy of not just cheating but having hidden cameras and making online porn….these are the messages plz tell me your unbiased opinion about how he responded…lol
