What do I do about my problem? How do i make her see ?

OK so here is the deal. I'm with my girlfriend (the love of my life ) we been together for 9 months now and Im not graduated from high school but I'm working hard on it. and I'm after a job that i so gloriously need and after that I'm going to A.V.C and then to U.C.R and I'm 19 turning 20 this year, shes done with high school , got a job going into the air force and she 20 turning 21 this year. she loves me and I'm not being coincided cause I know she loves with all her heart and i love her just the same or even more and she knows that but she says that shes thinking about her future and what would be the best course, she says that she living her life for her future as in marriage and kids, and I'm all for that.but what she says though is that right I'm not meeting most of her standards and that she loves me but she needs to think about her future and what she wants. I know what she means trust me but I want to be with her and I cant see my life without her. I want to spend the rest of my life with her. and I want her to be the mother of my children. I'm working on everything hopefully she doesn't give up on me cause I know I'm gonna get there. but how do i make her see that . and wait for me just a lil bit
