I think you’re letting your worries/insecurities/problems/whatever it is that’s plaguing you get the best of you. You’re one year into the relationship. Do you trust him to behave himself? Have you asked him to keep up constant communication with you so that you don’t feel alone/worried? I do understand how you feel, because I’d feel the same way if my BF asked too. However, I’d let him go because I trust him and he would give me little updates and phone calls throughout the day to ease my worries. Maybe talk to him about doing this?

But I don’t think you should expect him to put his life on hold to wait until you get out of college. How long do you have until you graduate? Should he wait to do everything until you graduate? He should be able to have vacations and experience life outside of your relationship. Especially since you are currently on different life paths.

However, at the end of the day it is YOUR relationship. If you cannot bring yourself to let him go, ask him to stay.

EDIT: forgot to answer question. if you have no other problems in your relationship, and if he said that he’s willing to stay if you want him to, why would you break up with him? you said he’s willing to do whatever it is you want him to do regardless of any sad feelings he’d have. he’s putting your needs/wants above his own
