So I need help here? With a girl? Five stars to a good answer....?

So, I was childhood friends with this girl. We were "married" and we hung out pretty much every single day. Once she kissed me when I was like 7, and I exploded and thought I was gonna die lol. So we stayed best friends, but when middle school came around, we kinda stopped hanging out. Then when highschool came around, we didnt talk at all. I always thought she didnt have a facebook. So she gives me a call the other day. Told me to friend her on facebook. We remeniced for like an hour about the old days and hanging out. She mustve told me a whole handful of times that we were gonna get married. She said I would date a few more "a**hole" girls and she will date a few more "loser" guys, then, "we will get married". I told her we should try again one of these days. She said I should go to senor prom with her. I was kinda debating it and she persisted that I do that. She told me she would talk to my mom and then call me back. So she calls my mom (whome shes great friends with) and told her she was going to marry me a whole bunch of times. So...riddle me this? Whats the story here? Would she date me? Does she actually wanna marry me one day? I never really wanted to get married. Im kind of a "move on" kinda guy, but make no mistake I would go out/marry her in a second. You see, Ive always loved her. I just kinda figured since I was such a loser as a kid, I blew it. Please help me!

We are both sophomores and we go to different schools btw. Though I dont dont quite understand why age would matter
