Tired of long term relationships

I’m 23 and I’ve been with my bf 8 years, since high school, now I’m just a year away to be an architect, and I’m starting to plan my life, what I’m gonna do, where I’m gonna travel, or even if want to be with him the rest of my life, ( I want to) but he’s in cloud 9, he already ended college, we’re beginning a business, and when I ask him for our future as a couple he just says “together babe” and I’m like 😶, I want us to be a team married or not but a team, but he makes me feel like I’m just his sex and kissing gf ☹️
