I have an big issue

Whats up? Today I have been faced with one of the biggest issues that I've had in a while. First off, let me start off with saying that i will be leaving for school in about a week. But anyway, as of now I have a boyfriend, but there is also a guy that i've been knowing for a minute and in the beginning we were talking. to make a long story short, nothing ever happened between us and he used the excuse that i was getting ready to leave for college. anyway, now that i have a boyfriend, this guy keeps coming back trying to get with me. I wont lie, I do like him but i really care for my boyfriend. I'm really confused right now. I dont know what to do. should i disregard my feelings for the other guy and continue to do what i have been doing. should i at least give it a chance. i'm so confused?
