Dont wanna be naive

So my fiance has had a big issue with disrespecting me and how I feel about certain things and I've taken him back numerous times... Well anyway I saw an email to him fro. pornhub saying, "Almost there! Your new pornhub account has been created, click here to verify!" He immediately freaked out on ME, snatched his phone calling me a stupid bitch etc etc. Just cause I questioned it. Hes saying its spam and his email "muuust" be hacked. Like come in. I'm not stupid. Im so heartbroken at his response to all of it. Got defensive right away and started calling me names cause I found it in HIS phone... :(
