help!! I really don’t know what to say

Well, my boyfriend has always had this problem of ditching me for his friends the entire time we’ve been dating (a bit over a year). His friends literally spend the night with him every night (we’re going to be seniors in high school so we still live at separate houses) and some of the day as well, if not the whole day. I’ve always had this feeling that his friends were more important to him than I am but it never really sinks in until he ditches me like he did today. He’s done it maybe 10 times now and he knows well that it makes me upset, but he continues doing it. Because of this, I told him I wanted a break to see if maybe THEN he will hear me out when I talk about how much it upsets me when he ditches me for his friends and here was his disappointing response:

I know some people are going to say that he doesn’t love or care about me but it’s so weird because when things are going good he’s literally one of the most loving people I know, but when things turn bad he acts like he couldnt care less. I really just don’t know what to say or do at this point.
