Me and my sister shares a car since we go to uni together but about a year ago, we started going out with our bfs and she left and stayed with her bf. It has been a problem lately for us to share the car. We;d have a schedule to follow but she doesn't keep to it and its driviing me crazy. Her bf would use the car too even though he has got his own car. When there is anything wrong with the car, i'm always suppose to send the car and pay for the service. I've no idea what i'd do since she treats me like a door mat. She'd call me and msg me everyday about the car and i'm up to my neck now. I just cannot stand the thought of seeing her now. I'm THAT stressed. She'd ask me to come home and pick her up and be her driver to go and do groceries when its my turn to use the car. And i've been really frustrated and feels really fed up so i've asked my dad to get me another car if its possible, maybe a cheap car or sth. We currently share a 60,000 AUD car. And he's said that he'd give me 5K if i want to. Now, my bf is pissed at me because i've been crying over what my sister always do to me, I have no idea what she's thinking. It's like she wants to prove that she can beat or win me by leaving me out from our group of frens. She'd ask me out together previously but it seems like she enjoys hanging out with her bf frens whom she doesnt talk to at all, since we've all hung out before. My mom actually said that my sister is desperately keeping the car because she wants to show off the car and the bf is obviously banking on to that because i've seen him drive it even without my sister. I feel so hurt and the last straw when there was one incident that left me so sad. She stays down the street behind my place and there was once when i knew she wanted to use the car so i purposely left the car at home and went to uni with my bf. I told her the car is at home so y dont u walk and if not, u can wait for me to come home. She did not tell me what time she wanted the car and she knew i'd be in uni that day. And so she walked over. There was one day when i wanted to use the car, and she's at home, she asked me to walk to her place. I felt so crushed and i asked her y, her reply was, u made me walk. I'm always crying over this when i talk or think about it. She;s my twin sister and i don know what is wrong and if its the bf who's behind this, He's quite famous about being calculative and is not well liked. My sister has always been the rebellious one and my dad lectured her about it but she doesnt wanna listen and thinks she is right. I'd told her she can have the car and she's telling me that she don't want it anymore and she's not sincere because i've heard of it countless time. Help me to lead a happy life without this affecting. I'm lucky on the other hand, i have a bunch of good gal pals and a good bf who has been very understanding except for a minor out burst of anger just now. He absolutely despise my sister for what she has done. We used to hang out with this bunch of girls but now the girls have all shunned her because they had seen what she is doing now. Help me to help her!! Sorry bout the rant!!
