<human>: My fiancé [28M] lent me [26F] his old phone to use since mine broke and a replacement was coming in the mail in a few days. It didn't take long to find his history of cheating - through Facebook, messaging apps, hookup websites, Tinder, emails soliciting sex both locally and on work trips, etc. It seems like this has been going on behind my back for the duration of our relationship and is probably still going on. To give you an idea.. he's slept with over 30 women during the three years we were together. I haven't approached him about it but I don't feel the need to. I already saw more than I needed to know and the relationship is over. He is away for the week at a work event and is coming back on Friday night. I expect to remove my personal belongings from his apartment before then. And for the record, I've been tested and am just waiting the results. 

Once people start to approach me as to why I've cut my ex out of my life without a word or even before they do, can I just blast out proof of his cheating to all our mutual friends/family and possibly even his Facebook side chicks? Scorched earth approach always a bad idea? I know all my friends and family will all be asking questions since we always seemed like the "ideal couple" and he'll play the victim very well. Plus, there's probably several women that he's involved with that have no idea the double life he leads..

Can you condense the text into a few key points?
<bot>: Fiancé cheated and is probably continuing to cheat. I have evidence of it all. Scorched earth approach always a bad idea?
