Lustful husband

Hi all. I’ll try and make this sweet and to the point. My husband and I are faithful Christians. We’re not perfect of course, but we are very much so faithful. Many months ago, i found my husbands been watching “Korn”. I confronted him, and he apologizes and says i was just bored and came upon it..it was the first time I’ve ever seen anything like so. We got passed it. With in mind what my boundaries were and how that makes me feel. Yesterday i was on fb and updating my info. I checked out his too just because i was curious (he has no photos on his fb. Just uses it for memes and entertainment). I happened to look at his following list, and he’s following a bunch of provocative women who show off their bodies and all that jazz… Of course i was devastated and angry. I confronted him, he lied about it. Said he wasn’t following anyone like that. I showed that proof and he had nothing to say (he was on his way to work) later he texted me and said. Yes. He followed those women, hes been praying about it because he felt convicted and God told her no more social media. He’s gonna destroy his family if he doesn’t stop. I was just flabbergasted because yes, i knew my husband wasn’t perfect but i never thought he’d be struggling with sexual impurities. Hes never made me feel as though i wasn’t enough or his eyes were elsewhere. I feel so hurt and just betrayed. We’ve been together for almost 6 years. Married for 3. Weeks have 2 girls. I don’t know if i can be with someone like this. How can i trust him??? I told myself maybe separate. If he can’t be a man after Gods heart, he don’t need your heart..thoughts? Advice? I am really going through it emotionally and could use a friend. Thanks.
