I just want to know is it normal to just push away your sister who has been there for you through literally EVERYTHING. My little sister and I were supposed to go to the park together yesterday but instead she ditched me for her boyfriend (whom she sees EVERY DAY). We haven't had a day to just hangout since they got back together in like September. She comes home from school and goes straight to her room. She doesn't come out unless it's to eat or go to the bathroom. The only time she does her chores is when she wants to go see her boyfriend. She babysat my cousin with me Thursday and on the way home she didn't say two words to me. I asked her if she was okay when we got home and she said she was fine just irritated because she didn't get to see him that day. I have NEVER ignored her or changed my plans with her for any of the guys that I've dated. What the hell is up with this?
