Boyfriend help!😭

I really really love my boyfriend, but I know he isn't the one. I really don't want to hurt him, but I don't want him out of my life just yet. I don't want to let go of him, but I can't shake this feeling that he isn't the one! He is so sweet and nice but something just seems off! Am I wasting my time? I don't know what to do😭😭 (btw I'm 17 years old!💁🏼👍🏼)
