Soul mate, or compatible souls, I don't know, but for whatever reason she has chosen the safe conventional route, for now, and no doubt she will do so again, to have the respectful life that everyone expects, at least family and friends.
Step sister or not, you are still doing what every other jilted, dumped lover, in the world has done, holding on to false hope of returning to what was, and NOT moving beyond it, and getting a life that you enjoy without her in it. Maybe she isn't into this guy as you say. Does that mean you wait for her to dump him, and come back to you? Of course not.
What you fail to take into account from her is that she is with him, for whatever reason, and will be with someone else later, just to have what all females want, after they have had their fun, a house and family. Imagine what your family, and hers, would say about anything to do with the two of you being a couple and you see why you are where you are, and she is where she is.
That stands out in your post, more than anything, that this affair was done without the knowledge of anyone but the two of you, and clearly she sees that. And just as clearly, she will keep it that way. That you ignore this very obvious fact is telling, as its the biggest fact you have. The rest are feelings, that may or may NOT last as long as you think.
For it to work the way you want, then you better have a plan that doesn't include family being a part of your life, which was the biggest obstacle you faced from the beginning. My advice is the same I give all after a failed relationship. Move on with your life and get your proper healing, and get a healthy, happy life without her. It was fun while it lasted, now its over. Stay out of her business, and stop looking for signs that the good old days will come back.
If you don't, you will be a secret lover forever. No way will she trade a life with you at the expense of family.
