Advice please!!!

My husband and i have been married for 3 years. He is a GREAT man and a wonderful husband. The only time we ever “fight” is over something to do with his family (he is employed by them and we live a mile down the road from them so there’s lots of tension). During my pregnancy he became distant, i blamed it on my crazy hormones because i was a basket case!! When our son was born, 6 weeks ago it ended in an emergency c section and was a very rough deal. While I’m laying in the hospital bed, i was looking on his tablet and discovered he had been watching porn y’all....not just once or twice. I brushed it off. Well today, i have discovered he has been watching it again and I’m furious and so so hurt. I feel like I’m not good enough for him. We have never had trust issues, he has never been unfaithful to me so this is just blowing me away because he is not this kind of person. Am i wrong to be so upset and angry at him for this? In the back of my mind I’m always going to think I’m not good enough for him. Please kind words would be greatly appreciated right now! Fighting PPD and this is the last thing i need on my plate!
