Me and my boyfriend have been together for like 9 months and a half. He told me since the beginning that he has been cheated on and he doesn’t want me to do it and how he would never think of doing it. We both lost our virginities to each other and he told me he never wanted to have sex or think about being with someone else. But I found messages on his SC that he sent nudes to a random girl and he’s been texting girls like 2 months into our relationship but I didn’t know. I confronted him and he said he was sorry and everything and I forgave him for that. But I told my friend to text him being all flirty. (She was not into it; had to convince with food). It was like a test to see if he would cheat on me with one of my bestfriends. And he did. She didn’t want to see or do the messaging so I did it on her SC. He sent them and I was texting him while it was happening. I was saying like you will never cheat on me right? And he would say right. But he was doing it in the moment. So I screenshotted most of the pics he sent then I blocked him for her. He told her to not tell me and she asked then why are you doing this. And he replied Bc I want to.

I confronted him about it and he says to just break up with him Bc he feels like he is going to do it again. But I don’t want to give up on us. Any advice?
