What should i do about this relationship i got myself into ?

i already now i'm just infatuated with her! but the problem is i never get attached to a girl and i am now! and did i mention i'm leaving for the navy in three weeks but i've only been with her a little over a month! i'm not gonna just quit the navy for her and we aren't gonna stay together but my question is should i spend every second with her from now until i leave and just think about her all threw boot camp or should i just break it off now and try and get over her before i leave???
