Honestly, I think it is pretty crazy to commit yourself to someone at age 19. I can definitely see how one might have a “taste the green on the other side” before everything closes in. I would say continue with her, at the same time make sure that your finances are somewhat separate and that you can support yourself in the lifestyle you want to live, even if shit hits the fan. Coming from a guy your age, with a gf of five years but a more vivid past (same as my GF)
