Dude... you're giving this girl, who is in high school and whom you broke up with, waaaay too much power in deciding your future. It feels like the most important thing in the world when you think you're in love, but you are probably not. Its cliche to say it, but everyone else will tell you the same thing. You know why? Because they have gone through early relationships like this. Trust me, do what you want to do, not what she "might" do. Let alone the fact that she is in high school and will want to experience her own life. Don't even tell me you want to be attached like this this early... Good luck though....
