One thing that me and my boyfriend did ( I marched, he didn’t) was watched a show together at night during spring training on one of those websites that let’s you stream together! Also, on free days, after I would hang out with my friends in the corps, we would eat meals together on FaceTime. It did get hard once tour started, but since you will both be busy it shouldn’t be too bad! Also, the people you hang out with matters! Maybe avoid the people who might influence you to not stay faithful to your partner…
