Help!

A little backstory..gave birth back in November hubby was home for a while. He was working on a photo project while home. Said he was organizing pics and uploading things to upstairs computer.

Last week happened to view hubby's phone while he was answering a friend back and I def noticed a top less woman, but wasn't fully sure. Asked him about it he got all weird and said no and it was in his text.

Also, last week hubby asked me to take a pic with a thong on...something I 1. Never wear and 2. Don't normally do. I probably would've if he hadn't been so curt about it and I wasn't just physically exhausted and touched out from the day with the baby.

This week he came home from work... is away from the house 13 hours a day (we have a now 11 week old). We had a quick dinner and he was upstairs in about 15 minutes. My assumption was he changing and coming back down to be with our baby. That is what normally happens. He didn't instead our baby was getting a bit fussy I then decided let's go upstairs and maybe you can hop in the bath with hubby. We go up and are on the stairs and I see hubby is masterbating. (Honestly don't care that he was doing so- I think its healthy and I'm post c section and have been having pain and just overall uncomfortable really being intimate recently.) The issue lies in that he went and did that before even hanging out with our baby. Before just hanging out.

I went on his computer the today because he's always so weird about the porn he watches but I wanted to see what he likes. I figure maybe I can see something and have an idea and maybe we can try to figure out how to both be satisfied since it's not as easy as before. I'm all for trying and figuring what works. Well I went on and found a file and there were hundreds of folders and thousands of pics/videos. Again no problem with porn, but when looking through he had several pictures if my best friend. She was stretching and just sitting on the floor. He took these while we were at her house so he could stretch with her. A 100% innocent thing. I was there. Then I found a folder with videos of one of his ex-step brothers moms - just chatting on the phone. Then I kept looking and found a folder of a girl I was friends either eons ago but she still chats/sexts one of our friends so not sure if he just sends to hubby or what. Then I found pics of my mom from when my parents got married. Father passed away and we have a crap ton of stuff still to go through including pics...... I do not care about porn but these are all people I know and it feels terribly disrespectful. Like I'm so beyond hurt. I don't know how to even respond. The photo project he was working on was THIS. I was pregnant when we went to my friend's for him to stretch... I had just given birth when he decided porn storage was an important postpartum task.

I'm at a loss and really don't know whether to tear him a new one when he gets home soon or let myself cool down first. If you've read this far please any advice appreciated.
