Does anyone just despise their sister in law? Who elses SIL is a brat? That just always seems to get what she wants but makes other peoples lives harder or just complains about everything under the sun? She also never speaks to me and pretends I dont exist. How would you handle the situation if you SO's sister just ignored your existance but tried to be really close to your SO? Help! I wish he would just stop talking to her as much so she learns we are a packaged deal. Is this wrong? Im just so over her rudeness, so why does she get to treat me bad and maintain a great relationship with her brother?
