This relationship has a big effect on you, but it might not be the one you would have hoped for. You're in need of personal transformation; during the course of your relationship you strive toward graduating to a new level in your life, toward finding your path and following it, but you find that your path conflicts with your lover's. They have a very strong idea of where they need to go in life, and they probably try to push their own ways onto you.
But what's right for you isn't right for them, as hard as that is to accept. They might have some very strong opinions (which they could forget are just opinions!) about where you're headed in life, and they react strongly against any moves you make in another direction -- which could actually illuminate that this is, in fact, the right direction for you to follow. To make this more clear, let's try an example: Say you want to be a writer, but your lover denounces that dream as wildly impractical and foolish. That, then, would actually be a sign that writing is just what you should do, despite their disapproval! This is the kind of battle you two wage with each other again and again. Do you let it lead to a breakdown in your relationship, or do you learn to accept your differences and encourage each other along your rightful path? It's up to you to choose.
