To Stay with the love and heart or to end it

My Boyfriend and I have been Dating for 5 years only one break up. I am to graduate with an associates degree and move onto another college possibly. Anyway my boyfriend has refrained from talking to me about what was bothering him till the other day, whats bothering him is that he thinks he misses the single life where he can meet new friends and go to a bar ( cause apparentlly i told him he couldn't do that, which i told him he could just be careful cause i understand that a 22 year old has to do his thing with the guys.) He Doesnt know if he can last the relationship, the distance traveling to see me from westchester to freeport. He cant take seeing each other only 1 a month ( but thats only happened once recentlly) then he thinks he just wants to work and sleep and thats all. im 20 years old, i can't drink in new york but i trust him with everything. i have no reason not to. He says he loves me so much and wants to marry at one point before this started. we were doing so well and i wanted to move in after my degree of associates was given and after one year of college in the new one. he has an attitude sometimes but its more like a tantrum of a little kid and well all have that sometimes. he doesnt want to put his work before me hes not sure if he wants to thrown in the towel and still wants me. but he doesnt know anything hes 50/50 on ending it and staying together. im mature enough to be reasoned and work things out and understand that somethings have to be changed for the better and take care of him all the time and he takes care of me. he doesnt want to travel and i do but i know im not going to go everywhere i hoped to but theres always vacations we can take together and drive somewhere. wants me to do good in school but he thinks hes distracting me and he couldnt do it anymore. i love him so much and i buy him sweet little gifts all the time and make him smile and feel that hes on top of the world and i tell him that i dont want to be with anyone else and hes happy, but now i dont know. i dont know what to do or where to go please help me!!! :(
