Disgusted

I dont even know what to do anymore. I dont know how to feel and dont want to feel anything 😩 its fine if you dont agree with things in this post but i ask you to hold your judgment. I went through my fiances website data last night and found a porn site. I instantly felt sick, i tried to chill for a second and just look it up hoping it was one of those false ad sites ie: foodporn ect. But its an actual site. My stomach sank. Not only did we have an agreement im not okay with porn so it is to stay out of the relationship, its a fucking beastiality site 🤢🤢🤢🤢🤢😷😷😓 i cant even begin to understand why this would happen, im so beyond repulsed and he's actually trying to deny he went on it. I feel so sick and need to just die on xanax 😭😭 i have no choice but to stay for a few days while i pack my things and gather my brain together again cause i cant bear the embarrassment of telling even family why its over yet, we were just about to get our first house im so beside myself.  Ladies please give me some insight. I dont even know who i was about to marry. 
Edit;;;; for all asking it was not a pop up. I can see the KB's (data) used for that site, and its far more than even cart part sites hes been surfing. I cant believe hes even trying to lie about it i feel like he thinks im dumb or something.
And his friends didnt send it. He has one friend and he wouldnt do that. His wife would ring his neck and i think thats some sick shit to be sending to a friend anyway.
Honestly you women saying its not a big deal? Really?? ITS FUCKING BEASTIALITY COME ON .Â
