It won't be easy and it rlly depends on both parties. If you're
the kind that needs a lot of attention from your bf then or might
be hard for you in the beginning. You just have to get used to
it.
My bf also enlisted last week and it's hard honestly everyday
just talk on the phone for 5 mins or even lesser sometimes. But you
will learn to appreciate him and the time spent even more. After he
enlisted I regretted all those times when we used to
quarrel.
