what should i do???

my boyfriends thinking of joining the marines and i’m pretty sad because i won’t be able to see him as often. 😢 i really love him, i really do but i just, i don’t know. i don’t think i could be away from him for a long time because i’m used to always being around him. ): what should i do? i’ve already told him how i feel about him going and he says that he hasn’t decided yet. i just don’t want him to go!! he’s really the love of my life and i don’t wanna lose him! 😔 i just don’t know what to do...
