I don't dislike my sister; I would (and have done) anything for her. Sadly, that is not mutual. She's very self-centred. She leaves me to do all the running around for the elderly members of the family and, whilst I am often the one to organise family events, she won't help but will take the credit (if she's even there). Despite the fact we live only a few miles apart, I think we have only met independently once in the last few years (and that was only because mum suggested it when we both happened to visit her at the same time). This year, I have given up trying to maintain contact as she often didn't reply, she's only messaged me a few times and that has been when she wanted something.
It does sadden me but I feel that she needs to pull her weight and rebalance the relationship. She doesn't have many friends (I would probably go so far as to say she doesn't have any friends nowadays) but I still think she needs to do her bit else I am going to grow to resent her.
