I'm sorry you're feeling this way. Although I only have one sibling with a PD, the rest of us have picked up fleas from our PD mother and can sometimes be difficult to deal with each other as siblings. I noticed two things about your post:
1. Lack of communication. I too have a sister that I don't see often as she lives out of state, and she has informed me she is coming for the Christmas holidays to our area. If for whatever reason she chose not to contact me during her visit, I too would wonder what was up. In my family, (as it sounds like might be the case in yours) the tendency is to ignore the slight, pretend to be unaffected, and move forward as if nothing happened. That way if the slight was intentional, the slighter wouldn't get the satisfaction of knowing they hurt you - a lesson we learned many times over from our NM. I no longer participate in this behavior, however, because it's unhealthy. If I was in a similar situation I would text or email (a phone call might make the other person feel cornered or criticized, and feels too confrontational to me, but it depends on your comfort level) and say, "Missed seeing you...was there a reason you weren't able to visit?" For all you know, she might have had a very valid reason. Or not. Either way, the responsibility is squarely where it belongs, and you've called her out on her rudeness, if that's what it is, regardless of her response.
2. Automatically assuming guilt or that you've done something wrong. Either you have or you haven't, and you'd know if you did.
You can't control anyone's behavior but your own. If your sister decided not to see you for whatever reason, it's her loss.
