Going into College

So me and my boyfriend have dated for over a year. He makes me so incredibly happy and is everything I want in a long-term relationship. We’re about to go to college soon (don’t know if we will be going to same school or not) but I don’t know if I should stay with him because he’s the only serious boyfriend I’ve had and I feel like I should dip my toe into some other relationships and experience college to my fullest. We have near perfect communication, good sex life, everything is great and I don’t want to ruin that. I just don’t know what I should do.
