What do I do...

My husband and I have been together for five years in total ( married for almost two). He’s my best friend and we’ve never had any issues besides one; porn. I personally don’t like him watching it and I get that it’s normal, but something about it makes me so uncomfortable. Well long story short I’ve caught him lying about it multiple times throughout our relationship and marriage, which always end in him promising not to do it again because he knows how much it upsets me. Well, fast forward to November. I found out I was around two months pregnant right before he left for a training for a month. I didn’t want to add stress by telling him right before he left so I planned a whole surprise announcement for him when he got back, because I wanted it to be special as it was going to be our first☺️ At the end of the first week of him being gone I miscarried. This has been my third, but I’ve never made it past the first month so I was even more devastated than the first two... I needed his support so I drove to see him and told him everything. He didn’t really respond and that made the situation worse... I came home even more devastated as it seemed it didn’t even bother him. When he came back I was wondering why he didn’t seem to care so unfortunately I went snooping. I found several different porn sites, which I assumed I would as he was gone a month, but I also found where he had downloaded a hidden photo/ video app and two apps similar to tinder. I confronted him and he said a friend had done it and the reason he didn’t tell me was because he knew I would get upset. A few weeks after I still couldn’t trust it and asked him again... he then said he did it because he wanted to talk to someone besides me about the miscarriage because he was devastated, but didn’t want to add stress to me. Here I am two weeks later still feeling like it’s a lie. I feel crazy for snooping, because I know I shouldn’t have. I feel so stupid for trying to trust him on this. I really need advice... I apologize for this being so long🤦🏻‍♀️
