Relationship question?

with being 15, most people would say that you are just feeling puppy love. im not one of them tho. i been with my girl since i was 15 and im bout to turn 17. im a hella shy guy. if you truely love her, then tell her that she is your life and you cant go even a minute without imagining the 2 of you spending the rest of your lives together. try coming up with your own idea so that its original and realy comes from your heart!! if you need any more advice, just e-mail me!!
