🚨Long distance boyfriend joining a frat?🚨

Does anybody have a long distance (or not) boyfriend who’s joining/joined a frat? We’ve been together for 2 amazing years & he’s my absolute best friend. We have a very committed relationship. But I still can’t help but be scared. He’s a pretty big partier but we always partied together and I feel like he’s gonna get caught up in that lifestyle heavily & make stupid decisions. He’s kind of like an all or nothing guy. I also feel like he’s never gonna have time for me with schoolwork & then everything that comes with a fraternity. I’d like to hear your guys experience or even someone you know experience on what to expect and how to deal with being scared/jealous, especially with him being across the country.

Edit: I’m 20 he’s 19. We lived together basically since the beginning of our relationship. I truly could see myself spending the rest of my life with him. Just some backstory, it’s a very serious relationship
