Thank you.
I am feeling wobbly this morning.
He has taken the children on the trip to PIL.
They of course all excited to be going on a trip. The PIL are odd, imo, (underparenting is part of the reason H is the way he is?) but they will look after childern very well so I have no worries on that front.
H is a fool, but I have no worries he 'wont bring them back' (he'd HATE to have to stop work and actually look after them, or anything.... a weekend 'being good daddy' in front of his parents is all he wants).
But.... as he knows, my father died when I was very young and for complicated reasons (my mother was unwell and couldn't look after me safely) it affected my life profoundly. Father died in car accident. I'm a bit twitchy about long car journeys therefore. H will be driving them between Scotland and Birmingham that's twitchville for me 
Also, as ds left today he was fighting back tears saying: 'maybe next time you'll be invited Mummy' (he is 10, but with SEN so a young 10). That's not right, is it? I know parents take their kids off on trips solo all the time, but his awareness I am not invited and his sadness about it was very sad to see.
Ds has, in the past, asked me if I was afraid of H. I didn't say yes, but I didn't say 'no' quickly enough, iyswim. He looked surprised and said: 'I'm only afraid of him because he is bigger than me'. (I am quite fat, so although H taller, in ds eyes he wouldn't be 'bigger than me'.) That worried me.
I don't want to stay in our house.
It is on 4 floors and I mobilise on crutches much of the time.
I have not been employed for some time, due to my health conditions and fact ds misses quite a bit of school unpredictably due to SEN.
Our local Education Authority provision for SEN is AWFUL -
(newsworthy scandal awful) and (H says I have 'rubbed them up the wrong way' but actually they have ignored 3 diagnoses now) a fresh start educationally for the children would actually be a good thing. I know too much change is never good but that is why we were moving anyway, it's just now I will need to go alone.
Because I am in Scotland, we have have a separation agreement that is legally binding as long as we have both taken legal advice.
Have been trying to sell house for 4 years. No joy.
He cant afford to buy me out.
Could possibly rent it and split proceeds which might go towards rental for me?
The practicalities of the split will be hard. I have NO money, am disabled and there are educational issues.
But what worries me most is that the children will hate me for leaving him.
When he is 'nice daddy' (and of course with me not being able to walk far, he has done many of the 'exciting' trips for years so they associate him with fun and me with 'eat up, brush teeth, do homework, tidy up - he ignores all that unless he explodes about it).
If I tell them we are leaving due to educational needs ds will 'blame' his SEN.
If I say we are leaving because I cant live with Daddy any more they will either think I am being selfish (it's not so bad?) or that I should have done it years ago (which I should ).
Sorry for muddle headed essay. Not much sleep.
