Would this make you upset?

My husband doesn't watch porn (that I know of). But, ever since we were dating he has an issue with looking at women on Facebook (like fitness type women) and also women on the Chive. Particularly women with big boobs and just nice bodies. You get the point. Anyways, I've confronted him numerous times about it. Well tonight I went on his phone (relax ladies he was in the room and I was looking up a quick video on a how to, full permission) and there were two Chive pages up with said women on them. He denied looking them up, still denies it, and has no reasonable explanation of how two different pages are up on his phone. Would you be upset? Does Chive really just pop in random stuff? Ugh, and of course I'm 6 1/2 months pregnant. Of course I'm crying. And on another note, and this shouldn't even matter, I have big boobs (thanks pregnancy) and I'm actually extremely fit. Any advice would be great. Right now I'm hiding out in the basement upset, and he knows it. I really don't know how to feel or even how to just deal with it. It's just a picture I know, but it means so much more to me.
