I broke it off

I broke it off with my fiance yesterday. It hurts but I can't turn the other way when I know I'm not just being paranoid as he says. I found pictures of another woman in his photos, no nudes but plenty of cleavage and stuff. I found out he talks to woman from plenty of fish on snapchat from a screenshot he took himself and saved in his photos. Recent convos from 4 months ago (I don't know about now because I didn't go through his apps, just his photos) after confronting him he denies everything and says I'm paranoid... am I really?
