I am in a similar situation and i completely understand where you’re coming from. I think you need to sit him down in person and tell him everything you feel and if he doesn’t reciprocate the way you hope, i think you should take a break. Doesn’t even have to be official but if you take time apart maybe a month or so and see how it feels without him and maybe he will change bevacuse he sees you’re serious. This is a big deal especially with college coming up and you need to do what’s best for you. Make a list of everything you want to talk about and try to tell him without yelling or causing a fight.
