Should we be together?!

Ok so I've been dating this guy for two years now. I've just graduated high school and I'm headed to college in about 20 days. Although I will be living on campus the school is only a 33 minute drive from my boyfriends location. For the last couple of months I've been trying to decide if I wanted to stay together during college... He's been a great boyfriend literally almost no flaws. I decided to ask for a break to help sort out my thoughts and figure out if our relationship is what I reall want. During the break I rekindled with an old flame and started to catch feelings. While mid break my bf called and told me either the break was over or we were over so I jumped back into the relationship.. Now I'm in the relationship and I think about my old flame and I'm not just not sure if my hearts in it.. But I'm afraid to break it off and it be the wrong decision... Help 😩
