Should I leave him or should I not?

Okay opinions from both es...I've known this guy for almost two years and I've been dating him for approximately 2 months. He is 17 and I'm 18. So I'm graduating but he still has another year. I'm leaving to go to University in the fall and I don't know if I should leave him or stay with him! Even if I did stay with him I wouldn't see him like ever! he has a year of highschool left and then he's gong to a different university then I am. ugh....Idk what to do. He left to mexico for 3 weeks and I missed him quite a bit. I really think I love him. Him and I have had several talks about what we should do but we haven't came to a conclusion. Opinions,..., PLEASE.
