Should I break up with my man

Ok here’s the tea sis... me and my boyfriend have been together for about 10 months and we’ve gone through a lot with each other, like forever scarring a lot together. However lately I’ve been feeling more and more distant from him and I honestly feel like I’m being smothered by him sometimes bc he’s still somehow in the honeymoon phase. He tends to go off on rants about my ex’s whenever they’re mentioned or makes me feel bad about being with them without even noticing. He’s a really good person but this is a high school relationship and he’s 100% convinced we’re going to get married. Someone give me some advice on if I should go on a break with him or not I’ve been so confused lately and I feel terrible.
