Unhappy Relationship

Ladies, can we talk? Me and my new boyfriend have been dating for 2 months now. And we've had serious problems. The first situation: At the time, we weren't able to talk to each other. But once I came back to social media after a couple weeks, I found out he cheated on me with 3 girls. But keep in mind, I was kind of liking my friend at the time BUT didn't do anything about it. We argued about everything for a week and resolved it. Then we were okay for a couple of days until situation 2 happened. Second Situation: I was texting my best guy friend and he is half Hispanic so we were texting in spanish. All of a sudden, boyfriend texts me saying "Devyne why are you and so and so talking in Spanish." I said "Because that's what we do." He ended up thinking that I was flirting with that guy and got mad. Boyfriend is blowing my friend up saying "Why are you asking my lady for nudes!?!?" Yes, my friend asked me for nudes and I told him no. Boyfriend is friends with my friend. I understand he's protective but still. I feel like I can't trust him and he can't trust me. So trust has been lost and We're trying to become better and fix it but let's be honest. I feel hopeless😥. HELP ME
