My sister is just a couple of years younger than me.
I thought we were really close, she was in a horrible relationship and she used to phone me for hours every evening.
I was always there on the phone for her even when it made my own relationship hard.
Her daughters school was round the corner from my home and I picked her up every day after school and looked after her until my sister came to collect her.
She knew I never even talked to her boyfriend.
I babysat her son for years until he went to nursery, listened to multiple hours of whatever every single day for years.
I would have done anything for her.
I had only moved to the house I lived in at the time as she begged me to live closer to her, so I uprooted my whole life because she needed me.
One day she went silent.
I was genuinely terrified for them and wondered if he had harmed them, she lived a few miles away and I went out there to find out if she was okay.
Turned out, we were not that close as far as she was concerned.
She'd planned for months to leave her ex and when she did she left me too, didn't tell me she was going, where she went, had found a new bloke hundreds of miles away to move in with and had never so much as mentioned him.
She'd changed her number, changed address, applied internally to move her job to a different location.
She got round to phoning me a few months later.
Didn't think going from being in my house 6 days a week with her kids and then on the phone for hours every single day to no contact was that big a deal.
Didn't think just letting me know that they were okay was something worth doing.
Obviously I didn't matter enough in her life to even be told.
It's never been the same since.
Our relationship now is very very fragile, which she doesn't seem to notice or care about.
Wish I didn't have a sister.
Not sure anything ever hurt me as much as she did.
I'd never have stopped her doing what she did, but the fact that she didn't trust me enough to have a clue what was going on, while she knew she was causing me problems in my own relationship with the amount of time she took up in my life really really hurts.
Now she has a better life a long way away from where I live, she rarely bothers to phone me unless she's at a loose end.
Every time she does, it just reminds me of how little I actually mattered to her when it counted.
