[QUOTE=Alishia88;3746889]I´m telling you, that she has changed intensely, and that it doesn´t seem healthy to me. I am concerned and sad that we can´t have a connection anymore because she´s not willing to be "personal" with me anymore.[QUOTE]
I understand what you're going through.
A very similar thing happened to me with my younger brother a few years back. After doing a bit of therapy, he painted such a rosy picture of my parents and our childhood, it was startling. I also understand the goofy "I'm all better" grin. Our home life was full of emotional and physical abuse and neglect not only from our parents, but our older sibs as well. When I first witnessed this behavior, my first thought was denial, denial, denial. (Nobody heals that fast from such a short stint of therapy.) The same thought is ringing in my head about your sister. It is also very unfortunate she is now bringing a child into the world with this unfinished emotional business.
Listen to your instincts. If it doesn't feel right it probably isn't. All that you can do is accept where your sister is at. This is what I did with my brother. We still talk, but not about our family issues.
An old saying I like goes like this: Healthy people are in therapy. Sick people are in denial.
