SO and Porn

I know guys like looking at porn, I get it. I’ve been with SO for 12 years, we are expecting baby #2 and I came across dozens of pictures on his phone and a few porn apps. He’s never had that many pictures saved in his phone or actual apps for it!

Idk if it’s because I’m hormonal but I feel like shit, I’m getting big while he’s staring at skinny chicks on his phone all the time.

Am I being ridiculous, over thinking it? He has never cheated on me, I don’t think he is, or will.

Thoughts? Ignore it? Say something?

TIA
