Do I still love him?

I've been going out with my boyfriend for just under a year now but things have started changed, I feel like I'm pushing him away and sex has completely stopped, everytime he wants to I'm just "not in the mood". Honestly I still love him but if people were to ask do you find him attractive I just get all clammed up and say no? I'm unclear if I still want to be with him and everytime I go to end it, he makes me think about the future we could have together.. But being with or without him makes me unhappy. I'm only 17, am I just dumb and in love or is he really the one?
