Should I Take A Break With My Boyfriend?

Angela
I need some advice. My boyfriend and I have been dating for almost 2 and a half years, and recently I've been wondering if he's really the one for me. He is unemployed (for about 6mo.) , and hasn't had much initiative to go out and apply to places, nor does he really want to go to college to improve his field of study. 
Also, whenever we're around, he treats me like I'm one of his guy friends, like showing me snapchat stories of other guys and their parties, and showing me inappropriate things on Instagram. He never comments on how beautiful I am when I send him pictures of myself, and he never posts WCWs of me on Instagram. He used to be the sweetest man in the world and would do anything for me and do anything I wanted to do, like roller skating and going to the mall. 
But now all we do anymore is eat fast food, and watch TV at his place and it's taking a toll on our bodies, and we have both equally gained weight. I love him even though I'm disappointed with him, so I'm iust wondering if I should take a break from him and see what happens or just ride it out?
