need advice

hey guys! I've never posted in here before and I'm hoping you could all give me some answers. so Im 17, and my boyfriend is 16. I'm a senior, he's a junior. we started dating the March of my sophomore(his freshman year). I feel like he is just keeping me around for his own needs (sexually) and doesn't love me anymore. he never says it and never compliments me in anyway, and I honestly just don't think I care anymore, but at the same time I can't imagine my life without him. I don't think it's wrong to want to be complimented by your boyfriend. there is a lot more to the story, and if someone would be willing to talk and help me I'd really appreciate it. thanks girls❤
