Found out last week.

Nothing's been sorted out yet as far as I can tell - mum's still in the house but will be moving down to England to be near her mum and her friends when she gets some money (she doesn't work so any money she gets will come from the separation), dad will be keeping our house so my sister and I will still be able to stay there, which is something I guess.
I think the worst thing at the moment is that there's so much I don't know - it's not my parents' fault, mum's trying to keep my sister and I as up-to-date as possible (dad's not really talking about it), but I have no idea when mum's leaving, what she's going to do when she gets there, whether she's going to find work, what's going to happen at Christmas (it's her relatives that come to visit us, doubt that's going to happen when she's not there), what's going to happen to the car my sister and I drive (which is owned by mum), and how this whole separation process actually works.

I'm away at uni at the moment so am feeling a bit disconnected from the whole thing, which is good in a way because I can carry on pretty much as normal but at the same time I hate not knowing what's going on.
And as irrational as it sounds, I'm also worried that this is a bad omen for my boyfriend and I.

My mum's parents split up as well after she left home, my boyfriend's parents are in the process of splitting up after 30 years of marriage...I know it doesn't mean we're definitely going to end up the same way, but the worry's still there.
Any support would be greatly appreciated, also anyone who could explain how the separation process works in the UK as well since I don't want to bug my parents too much about it...
