What should I do? Should I take him back?

I set my boyfriend up to see if he’d cheat. With my friend. He knows we’re good friends. So I told her to hang out with him in his car. I told her to flirt and say she’ll keep them a secret and she liked him and was jealous that me and him are dating. He had work until 1 am. During the day he kept telling her no. I won’t cheat. I love her and I’m so committed to our relationship. She said I’ll change ur mind tonight. He said then I’m not going. Then she said fine I just want to tell you something. He said ok. When he finished work at 1 am he told me he was going home. He was talking to me asking if I love him. I said yes. He said would u ever cheat on me. I said no. He told me some people were telling him that I was talking to this new guy. I said he’s a friend. He said is he trying to get with u? I said no going to lie to u, yes. He went to her house and she told me he talked about me for half an hour saying how he isn’t going to cheat on me, he loves me, doesn’t want to lose my trust, and that he can’t do that. She touched his hand, he yelled and he said don’t touch me. Then she told me he then started touching her thigh and they made out for 4 minutes. She told me he wasn’t into it, he looked mad, he said get out of my car, he said he had to go. She got out and he texted her and asked if she wants to do it with him. She said no condoms no sex and he said he’ll bring condoms next time. When he went home he told me then he grabbed some food. I texted him cheater. We called at 4 am and he said he’ll fix this. He said she used him, and took advantage of him. He said he gave her no consent. I said u had control. But you lost it. I told him how could he do this. He said he loves me, I was the best think that happened to him. He said he will fix it. He said he needs to. He said he will kill himself because of what he did. He said he’ll do anything and everything to make it work. He said he kept telling her he was in love with me. He was crying on phone. Me and him never had sex. We are 16. I said you could’ve waited for me. He said he waited for 6 months and he didn’t think I’d ever give him sex. He said he hates himself, he will never love himself, I deserve better, he said I find better, he said I talk to a lot of guys even tho they are friends, he has a lot of girl Friends. He said he’s insecure, and jealous, and he can’t control it. He was abused all his childhood and his mom sister hate him. His dad hit him, his mom hit him, now and when he was a kid, and his dad left since he was 13. His ex girls all took advantage of him, used him, and broke up with him. So all his past is fucked up. What do I do. I still really like him and I want him back. Should i?
