Relationship advice

My boyfriend and I got into a huge fight a few days ago. I’ve started to notice that he takes his frustrations out on me when things don’t go his way. We have been fighting over the pettiest things recently as well. But anyhow, on the night of his graduation we went out for drinks with his buddies. Everything was going smoothly until he started getting tipsy. One thing that irks my life is that he starts being super friendly with other females. He had a gold chain that said “grad” on it. While he was taking pictures with his friends this female walks up to him and starts touching on his neck and she proceeds to take his necklace off and she puts it on and walks away with it. I got sooooo heated, like come on where’s your curve game. But I kept my composure and just stayed quiet because I didn’t want to start a fight with him. The whole ride home I was just pissed and silent.

When we got to his house, he was expecting sex and I said no because I was mad at him. This pissed him off so bad to the point where he just started saying he’s tired of my shit and that I’m pushing him away. That I always exaggerate about everything. He even said we should just end our relationship because we are just too opposite. This broke my heart. I love him a lot and I just feel like I can’t even voice what I don’t like because he just always takes it as me being exaggerating or jealous. We’ve been together for almost three years. Any advice, ladies? I want to make this work.
