I am having a problem with my fiancés sister. We used to be real close and hang out all the time and all of the sudden we are no longer friends. The first problem was he was previously married and they had a child together and she was real close with his ex wife, so they still talk. Second, her old best friend is now my best friend and she was upset that she was not in the wedding and I was. They are no longer best friends because his sister is wild, drinks heavy and our once mutual friends has changed and for the better and she does not be on all the drama and mess. Thirdly, her brother has changed so much for the better since we been together and he is not the person he used to be when he was with his ex-wife. So far, she has sabotage a lot of people that may not come to our wedding because she is all in their ear and using that this is his "Second Marriage" as a reason for not attending and also because this is a destination wedding and does not understand why it is not local? She is conniving and a habitual liar and I am heartbroken and upset. I feel like sometimes she is a devil and put a Hoax on our relationship because ever since we have planned to get married everything has been in our way: From my health, car, workplace, home life and friendships. We do have a Premarital counseling set up soon so I do want to bring many of these concerns up.
HELP!!!!!!
