I'm not sure what thread to put this in. And forgive me for the novel I am about to write. I am an only child and have always wanted to have a sister. My FI has two sisters and when I found this out I was beyond excited by the idea that if we were to get married I would not only be getting the best husband but I would be gaining two sisters as well. They are younger, 18 and 21, than him and I (28), but not by much. When I started to spend more time with them (his family lives in a different city about an hour away) I realized that his youngest sister is sweet, caring, fun, and welcoming. His other sister is another story. She is possibly the worst woman I have met in a long time. She is catty, fake, materialistic (in the worst way), and she is constantly making snide and judgmental comments. In real life I do not tolerate women like this. I generally avoid them and will put them in their place in the nicest way possible if I am forced to spend time with them. FI dislikes her and agrees with the above. He mostly tries to avoid her. Basically, I am heart broken. I wanted so badly to gain a new family as well as a husband but the man of my dreams is unfortunately related to the devil. I could go on and on to elaborate just how awful she really is but it's too much. When I think of all the backhanded compliments, racist remarks, and how she treats not only strangers but her own brothers and sisters I honestly want to scream and then cry. I just keep hoping that maybe, someday, she will grow up and be tolerable. However, my FMIL is the grown up version so I'm not optimistic.
