advice when you miss your bf?

so my boyfriend of about 10 months is away on a cruise in the british isles while i’m stuck at home in illinois. he has no internet except when he gets to ports which in my time zone is about 4 am so we can’t talk much. when we do get to text i miss him more. he’s gone for two weeks and it kinda sucks. i know two weeks is a short amount of time really but it’s the first time he’s been gone since we started dating. does anyone have any tips so i can stop missing him so much? it would be greatly appreciated!
