Am I out of line for being annoyed at my sister??

So just a bit of background, my sister is 2 years older than me and up to about the age of 11 we use to be very close but then everything started to fall apart...

First she wasn't happy that I was moving into secondary school where she would see me everyday and she didn't want me to go anywhere near her or her friends and would tell me to f**k off(I was 11/12)

Secondly she will call me a c**t is I reply with a one word answer or take to long to reply.

Thirdly she has called my long term boyfriend a c**t and punched him because he wanted to know what to get me for my birthday??

Finally, we don't live with our mum and dad as we are both old enough to have moved out but she will call up my parents saying I have come round and sworn at her and been aggressive and that I don't deserve to be in the family just because I have to cancel plans due to work/ my personal family.

Obviously other little things have happened along the line but I have never sworn at her, hit her or done anything wrong towards her apart from one word answer( I don't see a problem with that)??

Am I out of line when she meant to be my sister but treats me like this?? She also does the same to my dad saying we both shouldn't be in the family as we treat her like shit but my mum knows we don't so won't take her side but will listen to my sister unlike anyone else.

P.S she never had a boyfriend last more than 4 months (she's 27 years old), is she jealous of me??
