There is basically no way to break up with your boyfriend or girlfriend without hurting them. But the best way to get out of it with them having little feelings is to tell them the truth and. Before you leave kiss them on the cheek and say goodbye. If you don't kiss him he will think you didn't like him what so ever. But if he got the kiss correctly he will understand that your leaving for a long time,or good. Anyway hope this helps :-)
