pornography

So my husband and I have been married almost a year and a half now. and we will be getting sealed in the temple this month(: before we got married he told me he had previously had an addiction to porn before he went on his mission, and then after as well. My husband is the best guy in the whole world and has the best intentions and I love him so much. But I was scared to talk bring it up and about a month ago I asked him for the first time how that was going. And he told me that overall it was good but a handful of times he had slipped up (meaning 3-5) over the course of our marriage, and we had previously talked about masturbation and I had said it was fine as long as he wasn't focusing on other things. Come to find out he was masturabting to erotic stories. But he has now apologized, and he says he know that the slip up happened when we stopped going to church (I was pregnant and had a hard time attending due to being so sick) Sorry I know this is kind of long, but he is doing everything to prove to me that he wants us and our family and the Lord and it isn't a problem for him anymore, and he loves me and the Lord. But I still can't help but feel a little betrayed and hurt but have been getting better. We have also put in place some things that make me feel more comfortable, like once a week I'll check his history, we read scriptures and pray every night together, no phone in the shower/bathroom, little things that make me feel better and he had no arguments or anything like that is so willing to do anything to make it right. Anyone else have similar experiences? I just feel completely alone as I don't want to tell friends and such.
