Long distance + military

Hi everyone! My boyfriend and I have been together for 2 years and we are inseparable we get along so well and he is my best friend. We rarely argue and our relationship is honestly perfect. He leaves for the navy in a couple of days and I’ve been so nervous for the long distance I worry so much, he’s my other half and I don’t think I can deal with being away from him. He’ll be gone for a year and a half for boot camp and school and after that who knows. I know I’ll be busy with college and we talked about everything together and we want to try long distance and we both cried because we’re scared of what will happen to us. I think I just need some reassurance I really love this boy. Anyone have a significant other in the military? Pls help :(
