How to maximize the relationship?

My boyfriend of a year and three months is leaving for college soon and we decided to end it when he moves out. It's more of a mutual decision considering I will be moving out to my college & we both just seem like we couldn't handle trying to stay together. You might ask "why don't you try long distance for a bit?" Well me and him know it in our hearts that we couldn't handle everything & breaking up not in person is not ideal. I prefer ending it cleanly face to face so closure is given and no what ifs linger. I love this guy a lot and I do see a future with him, but I just need to find the courage to move past him and focus on my own career goals for now. I really hate imagining him with another girl, so any tips for that??? I still hope that me and him can be in contact since I do genuinely care about his wellbeing and his family is always so nice to me. I also hope that me and him could give it another shot if we are stable and still up for it. Is that too unrealistic of me? :/ since I know my days are counting down with him, how should I make it the best days of our lives ?? Tips please :)
