Feelings going away

I've been with my boyfriend for 11 months. I definitely fell hard for him and I would've done anything for him. Now it's like I don't even want to talk to him anymore .. We're both working constantly and when I'm free and he is too, he turns me down. It feels like he doesn't try. I'm beyond tired of seeing him once a week (if I'm lucky). I get so jealous of other couples, and like I shouldn't have to be jealous of other relationships. I've tried breaking up with him but it doesn't work he will drop everything and come over. But when I'm not trying to dump him he puts everything before me. I don't know what to do it just bugs the heck out of me that he doesn't want to see me unless I'm trying to move on
