So upset

Ok so I had a miscarriage 3 weeks ago and am still coming to terms with that. I went back to work and started to develop covid 19 symptoms so I'm currently in self isolation. It's just me, my boyfriend and the dog. Recently I needed to use his phone, and before he gave it to me I saw him delete his history. So yesterday, I needed to use his phone yet again. Soo I decided to check his history. What I found was him looking at porn as well as typing in celebrity names and the word naked after them. I'm so upset. I've had such a shit time and he lied to my face when I first asked him about the history and then had to come clean when I admitted to checking his history. I feel so disgusting and inadequate as well as useless because of my miscarriage. Thoughts?
