Am I being unreasonable?
Like, honestly, what do you think?
I guess I should probably give a bit of background here.

For quite a few years, my older brother sexually abused me. When I finally told somebody, I was sixteen - very close to seventeen - and social services and the police got involved. He was made to leave the family home whilst the case was ongoing - basically, until I "decided" on whether or not I wanted to press charges, etc. My parents didn't want the police involved and at the time, I guess I didn't either. As soon as I turned seventeen, there was no more social services involvement and the police had no case either - seriously, I had a social worker for like three weeks - and he moved back in.
Since then, I've had nothing to do with him. I don't speak to him, look at him, even acknowledge his existence because he's not relevant to my life.

Lately, it's like he's been forced back into my life. I had to go to the doctors the other day and so did he - miraculously, the appointments were ten minutes apart so we ended up going in the car together with my parents. I can't stand the fact that we were in that close proximity, to be honest, but I didn't make a fuss. I just did what I always did and ignored him.
The next day it was my mum's birthday so on special occasions, I understand it's one of those things where I have to tolerate him, like I did last christmas. I had to sit around a table with him. Then today, I go to the shop with my mum to meet my sister and he suddenly shows up at Asda like "Oh, Dad said you were here." He NEVER goes shopping with us. Ever. So why he suddenly felt the need, I don't know. I felt so uncomfortable. I'd walk behind my mum, who was pushing the trolley and he was in front but he'd make it so he was behind her so I'd automatically move away from him and after five minutes I was getting so grumpy. Then I had to sit in the car with him home.

I understand that my mum wants to make it seem like we have a perfect family as well and that we're both her kids but sometimes, I get annoyed with her about things. Like saying, "Oh, go and ask ______ " and I just glare at her and sit down. And I've been entering this competition on a website lately where you enter four people's names to get a gift and she said "Oh, put ______ name down for one of them" and I'd already done the competition twice that day so I went "I'm bored of it, you do one." and she went "Just cause I said put _______" and I was like "....." because to be honest, that wasn't really the reason. The reason was that she wasn't understanding that the name's mean nothing even though I'd told her three times and she knows I can't stand HIM anyway so why even bring him up? It's like she wants me to talk to him and I'm sorry but I'm not.

If she wants us all to live in this house, it's this way because although I wouldn't say the abuse is as much an issue for me now as it once was, I still haven't forgotten and he's not sorry for it. To forgive someone, I think they have to be sorry or at least understand they were wrong but he just walks around all smug, as if it's his right. There are other things that have made me feel like this but I'm getting lazy typing.

Am I being unreasonable to just want to be left in peace away from him? Do you think I should be all "pally-pally" with him? I'm not hostile towards him - I just can't bring myself to speak to him. Admittedly, if I'm kicking up a fuss about not being able to find something and he passes it in my direction, I'll mumble the tiniest thanks but that's it.

Also, I do love my mum and my dad. It's just some things get to me so..

I don't even really need an answer for this, to be honest. I think I just needed a rant about it, sorry :L
