Should I break up with my girlfriend before leaving for basic training?

Tell her how you feel, that you love her and cherish her but you want to pursue your dream and you want her to stand by you and not against and you know it's hard but if you really believe that your love is true that you;ll be back for he wow I sound like I'm writing a romance haha but that's my opinion just be honest and truthful to her so i hoped this helped you and good luck.
