It was about a year ago that I started a thread asking for help, and I just really want to say thank you to everyone who offered support and opinions and advice, and who, ultimately, helped give me the strength and courage to leave. I'm not sure if anyone will remember me; I had to go very quiet for a while after I left, and my original thread had to be moved.
Don't want to give too much detail because I don't want to be identifiable, but basically, I'd been married for 12+ years, 2 DC, and I had discovered three years previously that my Husband had had an affair with a woman he met through work. Husband was a respected 'community leader', the OW a volunteer at a community project. I posted initially because I thought he was beginning another inappropriate relationship with another volunteer. I didn't mean to drip feed, but I know as the thread went on people began to help me face up to just how controlling and abusive my Husband had been throughout our relationship; rarely physically violent, but the emotional, mental, and financial abuse had escalated throughout.
In the last few weeks of our marriage, he became increasingly abusive, claiming he would have me sectioned, he would tell people I was an alcoholic / promiscuous / unfit mother (despite having no proof of me being any of these), and he would get custody of the children, if I left him. He began to act in a really intimidating and threatening way, and it turns out that he had been spreading rumours about me; that I was a 'functioning alcoholic' (I barely drink alcohol), or had been having an affair (I wasn't, and since he didn't allow me to have male friends or indeed socialise with any friends, I don't know how I could have had one)
I contacted Women's Aid who believed me and took me seriously. They offered me space in a refuge. I chose to go and stay with family, took the children, and left one evening when my Husband was out.
My family, friends and work colleagues have been amazing.
On the negative side, I've been through a really difficult time with family court. CAFCASS didn't believe XH had been abusive (although I'd been to my GP who had directed me to Women's Aid, I'd never reported him to the police, since he wasn't physically violent) and recommended shared residency. It's very difficult. I miss the children and worry about them when they are in his care. However I know that they will now tell me if he hurts them or if they are worried or scared when they are with him. XH still tries to control me through them, but it's not really working since they are beginning to be old enough to have their own opinions about things. Financially, I'm still living with the debt XH built up, unknown to me; he spent all our savings, and incurred some other joint debts. But I try not to think about that, what's done is done, in a few years time i will have paid off my share and, to be honest, I'd pay it twice over and live on beans on toast to be free of him.
On the positive side...I did manage to divorce on grounds of unreasonable behaviour, and the relief of knowing I am free is just incredible. I wake up every morning feeling incredibly peaceful. I sleep well, I wake up feeling refreshed. I've lost weight (didn't mean to!) taken up sport again, and can go out with my friends or have friends round whenever I want. People keep telling me I am glowing.
It turns out I don't have SAD, I guess it was just a sense of dread at facing another dark winter with XH! Work paid for me to have twelve sessions of counselling, which helped me realise just how abusive things had been and helped me find ways to cope and begin to rebuild me life.
And...I have just started very cautiously dating a someone who I have been friends with for a while, it's early days, but for now, i'm just enjoying going for coffee or out for dinner with someone who is kind and respectful and understands that we need to go slow... 
So. I wanted to say thank you. AnyFucker you posted, and so did loads of others, and you helped me face up to the reality of what I had been going through.
