My boyfriend has been acting different towards me : Advice?

I need advice! -so my boyfriend of 8 months has been acting very different. Lately, he’s getting so mad easily; it seems he’s getting a little more comfortable with yelling at me and calling me names. With the past experiences that I’ve had, I automatically assume he’s cheating. He keeps telling me to leave his house, telling me he’ll find someone better than me “easily”. I’m starting to feel stuck. Helppp
