Don't know what to do...

Okay please don't give me shit for this cause I'm giving myself enough of it. My boyfriend of a year and a half is breaking up with me. I know that may not seem like a long time to know someone or know true love but that's what he is for me. He's my first time and he's helped me through so so much; same goes for him.  He is going into the navy which I completely support and tell him to do what he wants in his career path, ya know? Do what makes you happy. I am figuring out what I want to do and pretty much have a set path. Last month he spent a while with some family he hasn't seen in years, mind you he comes from a very strong family. His uncles brought up the navy pretty much so he has his mind set on it. Anyway. He says he doesn't have time for a relationship or energy, that stuff. But even his family has told me he's grown better as a person since he's known me. I'm so lost right now. I'm sorry if this is/was hard to keep up...I'm all over the place right now and trying to cope. What do I do 💔
