Future Marine Wife?

Anyone here married to someone in the marines ? If so what age did he propose at . I am about to be 17 we have been together for a year . he just graduated & is off to boot camp in september . he is hinting off when he comes back that he wants to propose ? Which I would do in a heartbeat , i know everyone has their opinion on it . About young marriages never last , but i have seen them last . I just wanna know another experience to base it off of . I love this guy with all my heart . & I know I do . I’ve been through so much , to where people think im crazy bc I want to settle down so fast . but i know what i want for my life & my future family .
