My husband has been watching porn 😔

Long story short, I have ZERO sex drive and I don’t even want my husband within 10 feet of me since becoming pregnant. I’m 18, almost 19 weeks and we have had sex 2 times since I found out I was pregnant (I had an early MC in September so I have been terrified to do ANYTHING this time around). Well this morning, our 5 year old had his phone and was asking me to find a video she had been watching on YouTube, so I went into his browser history to find the video..and I found multiple links to porn. “Big lipped blow jobs” to be exact. I was in shock, and quickly closed out of the window. But now, I’ve been stewing on it ALL day, unsure if I should say anything or not. I partially feel responsible because I haven’t been attentive or affectionate AT ALL, and I guess it’s better than a physical affair..right? I don’t know, I have no idea how to handle this situation..and I KNOW beyond a shadow of a doubt that if I bring it up he will say something about how I don’t ever want to have sex and I feel like that would just hurt me even more. What would YOU do? Please help!
