Falling out of love

My boyfriend and I have been together since 7th grade. We’re going to graduate next year.

Our relationship has been pretty good but i don’t know how to explain it.. I love him but I just feel so out of love and out of tune with him. We’ve been living together since October of 2020, so I really know him well. He’s really a great person, and showers me with gifts and anything I’ve wanted. But sometimes, (and honestly I mean all the time) he touches me. He touches my body inappropriately, like my boobs, my butt, my lady regions, and I really really don’t like it. Like sometimes I just want to cuddle.. why does it always have to be about that stuff? I hate it I really do. I guess I’m ranting now lol. He also never really wants to take walks with me. I know that’s stupid but I really enjoy walks. He says he’s too tired after practice or work.. i get it. But what hurts is he will go to his sisters house and change her tires after practice or work.. but can’t go on a walk with me because he’s “tired”. There’s other examples too I just can’t think of them rn. Gosh reading this.. you guys probably think he’s awful. Maybe he is and I just don’t see it. I don’t know.. i feel so lost about this relationship. Him doing that stuff makes me feel like I don’t love him. I don’t even want to have sex anymore. And that’s not normal.. I’m only 17!! Gosh what do I do?!?! It’s been almost 5 years.. and I don’t want to feel like I’ve wasted my time. I love him so much and I’ve grown up with him but recently I feel no spark anymore.
