Need advise

Hello- my husband and I have been together 5 years and married for almost 4. We have a 3 year old daughter and I’m currently 21 weeks pregnant. I got on my husbands phone today and found a secret photo album of naked women. Says he screenshotted them off of a Facebook group he was on. He swore on my unborn child that they were all extremely old. I looked at the time stamps and they were all from 2 weeks ago to last December. So I guess he advise I need is what to do? He deleted his snap chat (which there were girls on there as well) and his facebook. In everyone’s opinion is this something we can move on from or is this a deal breaker? I don’t know if I’m old school but I don’t agree with porn or anything like that. I would have sec with him any time of the day but he never wants too... I just feel like he’s been cheating for the last several months. What to do!!!

Let me add in this, I think looking at porn behind my back is in my book cheating... if we were to watch together it would be different but he says porn Is disgusting. But then was on it and on multiple sites of naked women and screenshotting there photos and saving them, also every time he looked at them we had sex afterwords (the time stamps on pictures go along with the dates my period tracker app says we had sex)
